feat(search): add server-side full-text search using MiniSearch
- install minisearch - add SearchIndex service with field-weighted indexing - sync index on recipe CRUD via RecipeService - new GET /api/recipes/search endpoint with pagination and ranking - unit tests for SearchIndex - remove erroneous FTS5 schema changes (revert to ADR-001 compliant approach) Search is now fast, pure JS, works with sql.js, respects privacy (server-side).

# FTS5 Full-Text Search — Execution Board
|
||||
|
||||
**Feature:** Add true full-text search (FTS5) to Recipe Manager
|
||||
**Created:** 2026-03-30
|
||||
**Status:** Planning → In Progress
|
||||
**Orchestrator:** Cleo (main agent)
|
||||
**Target Model:** stepfun/step-3.5-flash (where applicable)
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Goal
|
||||
|
||||
Replace the current `LIKE`-based search with a high-performance, relevant FTS5 virtual table that indexes:
|
||||
- Recipe titles and descriptions
|
||||
- Ingredient items and notes
|
||||
- Step instructions
|
||||
- Tag names (via recipe_tags join)
|
||||
|
||||
Provide a single backend search endpoint that:
|
||||
- Supports phrase queries, prefix searches, AND/OR logic
|
||||
- Returns ranked results by relevance
|
||||
- Preserves pagination metadata
|
||||
- Falls back gracefully if FTS fails
|
||||
|
||||
---
|
||||
|
||||
## 📦 Deliverables
|
||||
|
||||
1. **Schema & Migration**
|
||||
- Add `recipes_fts` virtual table (FTS5) with `title`, `description`, `ingredient_item`, `ingredient_notes`, `step_instruction`, `tag_name` columns
|
||||
- Create triggers to keep FTS in sync on INSERT/UPDATE/DELETE of recipes, ingredients, steps, tags, recipe_tags
|
||||
- Backfill existing data in migration
|
||||
|
||||
2. **Backend Search Endpoint**
|
||||
- New route: `GET /api/recipes/search`
|
||||
- Params: `q` (query string), `page`, `limit`
|
||||
- Uses `MATCH` with `bm25()` ranking
|
||||
- Returns `{ results, total, page, limit, hasMore }` consistent with existing list endpoint
|
||||
|
||||
3. **Frontend Integration**
|
||||
- Update search input to call new endpoint instead of filter-based search
|
||||
- Show ranked order (highest relevance first)
|
||||
- Preserve existing pagination UI
|
||||
|
||||
4. **Tests**
|
||||
- Unit tests for FTS trigger logic (insert/update/delete sync)
|
||||
- Backend integration tests: search relevance, phrase queries, no-results, pagination
|
||||
- E2E test: search returns expected recipes by title/ingredient
|
||||
|
||||
5. **Migration & Rollback**
|
||||
- Ensure `schemaVersion` increment and migration applied
|
||||
- Document rollback steps (drop virtual table + triggers)
|
||||

|
||||
|
||||
## 🧩 Dependencies
|
||||
|
||||
- T3 depends on T2 (endpoint requires schema)
|
||||
- T4 depends on T2 (tests need DB structure)
|
||||
- T5 depends on T3 (frontend calls endpoint)
|
||||
- T6 depends on T5
|
||||
- T7 depends on all
|
||||
|
||||
Tasks T1 and T2 can run in parallel (T1 designs, T2 starts once design is signed).
|
||||
|
||||

|
||||
|
||||
## 📐 Acceptance Criteria
|
||||
|
||||
- ✅ FTS5 virtual table present and populated with all existing recipes
|
||||
- ✅ Search returns recipes ranked by BM25 (most relevant first)
|
||||
- ✅ Phrase queries ("chocolate chip cookies") match correctly
|
||||
- ✅ Prefix searches ("choc") work
|
||||
- ✅ Ingredient-only searches return correct recipes
|
||||
- ✅ Pagination metadata consistent with list endpoint
|
||||
- ✅ All tests pass (including new FTS tests)
|
||||
- ✅ Rollback documented and tested (optional)
|
||||
|
||||

|
||||
|
||||
## 🛠️ Technical Notes
|
||||
|
||||
- Use `CREATE VIRTUAL TABLE recipes_fts USING fts5(...)`
|
||||
- Triggers: `AFTER INSERT/UPDATE/DELETE` on recipes, ingredients, steps, tags, recipe_tags
|
||||
- Use `content=''` and `content_triggers` to auto-sync if desired; but explicit triggers may be simpler
|
||||
- Migration must be idempotent (check if FTS exists before creating)
|
||||
- Backend: parameterized query `SELECT ... FROM recipes_fts WHERE recipes_fts MATCH ?`
|
||||
- Rank: `bm25(recipes_fts)` ascending (lower score = better)
|
||||
- Join back to `recipes` table to fetch full recipe objects
|
||||
|
||||
---
|
||||
|
||||
## 🧠 Success Metric
|
||||
|
||||
Search accuracy > current `LIKE` filter, no regressions in performance, tests green.
|
||||
|
||||
---
|
||||
|
||||
**Orchestration Plan:**
|
||||
Main agent will spawn seven independent sub-agents (one per task) with clear primitives. Sub-agents will report back with status updates. Main agent will monitor progress and roll up into a final status. Use `stepfun/step-3.5-flash` for all sub-agents where model choice applies (per instruction).

# FTS5 Virtual Table Schema & Trigger Plan — Design Spec
|
||||
|
||||
**Task:** T1: Design FTS5 virtual table schema + trigger plan for Recipe Manager
|
||||
**Created:** 2026-03-30
|
||||
**Target:** Implementation blueprint for T2 (migration)
|
||||
**Schema baseline:** `src/backend/db/schema.sql` (2026-03-28 MVP normalized)
|
||||
|
||||
---
|
||||
|
||||
## 1. FTS5 Virtual Table Definition
|
||||
|
||||
### Table Name
|
||||
`recipes_fts` — virtual table using FTS5 extension.
|
||||
|
||||
### Columns (for full-text indexing)
|
||||
Each column corresponds to a searchable text field from the recipe domain:
|
||||
|
||||
| Column | Source | Description |
|
||||
|--------|--------|-------------|
|
||||
| `title` | `recipes.title` | Recipe title (primary identifier) |
|
||||
| `description` | `recipes.description` | Recipe description/brief |
|
||||
| `ingredient_item` | `ingredients.item` aggregated | Ingredient names (e.g., "chicken", "flour") |
|
||||
| `ingredient_notes` | `ingredients.notes` aggregated | Ingredient-specific notes (e.g., " diced", "to taste") |
|
||||
| `step_instruction` | `steps.instruction` aggregated | Cooking step instructions |
|
||||
| `tag_name` | `tags.name` aggregated via `recipe_tags` | Tag names associated with the recipe |
|
||||
|
||||
### Tokenizer Configuration
|
||||
```sql
|
||||
CREATE VIRTUAL TABLE recipes_fts
|
||||
USING fts5(
|
||||
title,
|
||||
description,
|
||||
ingredient_item,
|
||||
ingredient_notes,
|
||||
step_instruction,
|
||||
tag_name,
|
||||
tokenize='porter unicode61'
|
||||
);
|
||||
```
|
||||
|
||||
**Rationale:**
|
||||
- `porter` stemming: reduces words to root forms (e.g., "chopped" → "chop", "chicken" stays "chicken", "sautéed" → "saut"). Improves recall for cooking terminology.
|
||||
- `unicode61` tokenizer: handles international characters and emoji (common in recipes) robustly.
|
||||
- Combined as `porter unicode61` → apply porter stemming with Unicode support.
|
||||
|
||||
### Rowid Mapping Strategy
|
||||
- The FTS table uses `rowid` to reference the corresponding `recipes.id`.
|
||||
- We will store `recipes.id` as the `rowid` directly: `INSERT INTO recipes_fts(rowid, ...) VALUES(recipe_id, ...)`.
|
||||
- This enables efficient joins: `SELECT r.* FROM recipes r JOIN recipes_fts fts ON r.id = fts.rowid WHERE fts MATCH ?`.
|
||||
|
||||
---
|
||||
|
||||
## 2. Trigger Design
|
||||
|
||||
We need triggers on all base tables to keep `recipes_fts` synchronized with aggregated data. The FTS table rows must be kept up-to-date whenever any underlying data changes.
|
||||
|
||||
### General Pattern
|
||||
For any recipe, its FTS row contains a **snapshot** of aggregated ingredient items/notes, step instructions, and tag names at that moment. On any change to related data, we must recalculate the aggregated content and upsert into `recipes_fts`.
|
||||
|
||||
### Helper SQL Functions
|
||||
|
||||
We recommend creating SQL functions to encapsulate the aggregation logic:
|
||||
|
||||
```sql
|
||||
-- Aggregate ingredient text for a recipe
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_ingredients(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(item || COALESCE(' ' || notes, ''), ' ')
|
||||
FROM ingredients
|
||||
WHERE recipe_id = recipe_id;
|
||||
END;
|
||||
|
||||
-- Aggregate step instructions for a recipe
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_steps(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(instruction, ' ')
|
||||
FROM steps
|
||||
WHERE recipe_id = recipe_id
|
||||
ORDER BY position;
|
||||
END;
|
||||
|
||||
-- Aggregate tag names for a recipe
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_tags(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(t.name, ' ')
|
||||
FROM tags t
|
||||
JOIN recipe_tags rt ON t.id = rt.tag_id
|
||||
WHERE rt.recipe_id = recipe_id;
|
||||
END;
|
||||
```
|
||||
|
||||
These functions can be called from triggers to reconstruct the aggregated content efficiently.
|
||||
|
||||
### Trigger Definitions
|
||||
|
||||
#### 2.1 Triggers on `recipes`
|
||||
|
||||
**Purpose:** Update FTS row when recipe's title or description changes.
|
||||
|
||||
- `recipes_after_insert`: Insert initial FTS row for new recipe.
|
||||
- `recipes_after_update`: Update FTS row if title/description changed.
|
||||
- `recipes_after_delete`: Delete FTS row when recipe is removed.
|
||||
|
||||
```sql
|
||||
-- AFTER INSERT on recipes
|
||||
CREATE TRIGGER recipes_after_insert
|
||||
AFTER INSERT ON recipes
|
||||
BEGIN
|
||||
INSERT INTO recipes_fts(rowid, title, description, ingredient_item, ingredient_notes, step_instruction, tag_name)
|
||||
VALUES (
|
||||
NEW.id,
|
||||
NEW.title,
|
||||
NEW.description,
|
||||
fts_aggregate_ingredients(NEW.id),
|
||||
fts_aggregate_ingredients(NEW.id), -- same aggregation, we'll separate items/notes below
|
||||
fts_aggregate_steps(NEW.id),
|
||||
fts_aggregate_tags(NEW.id)
|
||||
);
|
||||
END;
|
||||
|
||||
-- AFTER UPDATE on recipes (only when title/description change)
|
||||
CREATE TRIGGER recipes_after_update
|
||||
AFTER UPDATE OF title, description ON recipes
|
||||
WHEN OLD.title != NEW.title OR OLD.description != NEW.description
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET
|
||||
title = NEW.title,
|
||||
description = NEW.description
|
||||
WHERE rowid = OLD.id;
|
||||
END;
|
||||
|
||||
-- AFTER DELETE on recipes
|
||||
CREATE TRIGGER recipes_after_delete
|
||||
AFTER DELETE ON recipes
|
||||
BEGIN
|
||||
DELETE FROM recipes_fts WHERE rowid = OLD.id;
|
||||
END;
|
||||
```
|
||||
|
||||
**Note:** The `ingredient_item`, `ingredient_notes`, `step_instruction`, and `tag_name` fields will be maintained by other triggers on their respective tables; we only need to insert them initially here.
|
||||
|
||||
#### 2.2 Triggers on `ingredients`
|
||||
|
||||
**Purpose:** Recalculate aggregated ingredient content for the associated recipe whenever ingredients change.
|
||||
|
||||
- INSERT: update recipe's FTS row
|
||||
- UPDATE: if recipe_id changes, update both old and new recipes
|
||||
- DELETE: update recipe's FTS row
|
||||
|
||||
We need to aggregate `item` and `notes` into separate columns (`ingredient_item` and `ingredient_notes`) but with space linkage (`item || ' ' || notes` for `ingredient_notes`? Actually spec says `ingredient_notes` column should contain notes only? Let's review:
|
||||
|
||||
The execution board specifies columns: `ingredient_item`, `ingredient_notes`, `step_instruction`, `tag_name`.
|
||||
|
||||
Interpretation:
|
||||
- `ingredient_item`: concatenated list of ingredient item names (without notes)
|
||||
- `ingredient_notes`: concatenated list of ingredient notes (only the notes text)
|
||||
|
||||
But for search relevance, it's more useful to combine both: search for "diced" should find recipes with "1 cup diced onions". If we separate them, the note "diced" may not match the item column. However, we can index both separately; the query will search across all columns. So we can store pure items in `ingredient_item` and pure notes in `ingredient_notes`. The FTS query `MATCH` searches across all columns by default if you query a single column or use `recipes_fts MATCH ?` without column spec. But we might want to weight columns differently? That's an advanced optimization not required now.
|
||||
|
||||
Given the spec, I'll implement:
|
||||
|
||||
- `ingredient_item`: `GROUP_CONCAT(item, ' ')`
|
||||
- `ingredient_notes`: `GROUP_CONCAT(notes, ' ')` (excluding nulls)
|
||||
|
||||
```sql
|
||||
-- Helper to get aggregated ingredient item text
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_ingredient_items(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(item, ' ')
|
||||
FROM ingredients
|
||||
WHERE recipe_id = recipe_id;
|
||||
END;
|
||||
|
||||
-- Helper to get aggregated ingredient notes text
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_ingredient_notes(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(notes, ' ')
|
||||
FROM ingredients
|
||||
WHERE recipe_id = recipe_id AND notes IS NOT NULL AND notes != '';
|
||||
END;
|

|
||||
-- AFTER INSERT on ingredients
|

CREATE TRIGGER ingredients_after_insert

fts_aggregate_steps(r.id),
|
||||
fts_aggregate_tags(r.id)
|
||||
FROM recipes r
|
||||
WHERE r.id = NEW.recipe_id AND NOT EXISTS (SELECT 1 FROM recipes_fts WHERE rowid = r.id);
|
||||
END;
|
||||
|
||||
-- AFTER UPDATE on ingredients
|
||||
CREATE TRIGGER ingredients_after_update
|
||||
AFTER UPDATE ON ingredients
|
||||
BEGIN
|
||||
-- If recipe_id changed, update both old and new recipe's FTS rows
|
||||
UPDATE recipes_fts
|
||||
SET
|
||||
ingredient_item = fts_aggregate_ingredient_items(NEW.recipe_id),
|
||||

ingredient_notes = fts_aggregate_ingredient_notes(OLD.recipe_id)
|

WHERE rowid = OLD.recipe_id AND OLD.recipe_id != NEW.recipe_id;
|
||||
END;
|
||||
|
||||
-- AFTER DELETE on ingredients
|
||||
CREATE TRIGGER ingredients_after_delete
|
||||
AFTER DELETE ON ingredients
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET
|
||||
ingredient_item = fts_aggregate_ingredient_items(OLD.recipe_id),
|
||||
ingredient_notes = fts_aggregate_ingredient_notes(OLD.recipe_id)
|
||||
WHERE rowid = OLD.recipe_id;
|
||||
|
||||
-- If recipe has no ingredients now, we still keep the row (other columns may exist)
|
||||
END;
|
||||
```
|
||||
|
||||
#### 2.3 Triggers on `steps`
|
||||
|
||||
```sql
|
||||
-- AFTER INSERT on steps
|
||||
CREATE TRIGGER steps_after_insert
|
||||
AFTER INSERT ON steps
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET step_instruction = fts_aggregate_steps(NEW.recipe_id)
|
||||
WHERE rowid = NEW.recipe_id;
|
||||
|
||||
INSERT INTO recipes_fts(rowid, title, description, ingredient_item, ingredient_notes, step_instruction, tag_name)
|
||||
SELECT
|
||||
r.id,
|
||||
r.title,
|
||||
r.description,
|
||||
fts_aggregate_ingredient_items(r.id),
|
||||
fts_aggregate_ingredient_notes(r.id),
|
||||
fts_aggregate_steps(r.id),
|
||||
fts_aggregate_tags(r.id)
|
||||
FROM recipes r
|
||||
WHERE r.id = NEW.recipe_id AND NOT EXISTS (SELECT 1 FROM recipes_fts WHERE rowid = r.id);
|
||||
END;
|
||||
|
||||
-- AFTER UPDATE on steps
|
||||
CREATE TRIGGER steps_after_update
|
||||
AFTER UPDATE ON steps
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET step_instruction = fts_aggregate_steps(NEW.recipe_id)
|
||||
WHERE rowid = NEW.recipe_id;
|
||||
|
||||
UPDATE recipes_fts
|
||||
SET step_instruction = fts_aggregate_steps(OLD.recipe_id)
|
||||
WHERE rowid = OLD.recipe_id AND OLD.recipe_id != NEW.recipe_id;
|
||||
END;
|
||||
|
||||
-- AFTER DELETE on steps
|
||||
CREATE TRIGGER steps_after_delete
|
||||
AFTER DELETE ON steps
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET step_instruction = fts_aggregate_steps(OLD.recipe_id)
|
||||
WHERE rowid = OLD.recipe_id;
|
||||
END;
|
||||
```
|
||||
|
||||
#### 2.4 Triggers on `tags` and `recipe_tags`
|
||||
|
||||
Because tags are many-to-many, changes to tags can affect multiple recipes:
|
||||
|
||||
- INSERT tag: no recipes yet, nothing to do.
|
||||
- UPDATE tag name: affects all recipes linked to that tag.
|
||||
- DELETE tag: affects all recipes that had that tag (via ON DELETE CASCADE on recipe_tags, but before the tag row is removed, we need to update FTS for those recipes).
|
||||
|
||||
For `recipe_tags`:
|
||||
|
||||
- INSERT: affects the recipe (and possibly the tag, but tag name is used). The recipe gains a new tag → need to update its `tag_name` column.
|
||||
- DELETE: recipe loses a tag → need to update its `tag_name` column.
|
||||
- UPDATE on `recipe_tags` (rare): combination of delete + insert.
|
||||
|
||||
```sql
|
||||
-- AFTER INSERT on recipe_tags
|
||||
CREATE TRIGGER recipe_tags_after_insert
|
||||
AFTER INSERT ON recipe_tags
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET tag_name = fts_aggregate_tags(NEW.recipe_id)
|
||||
WHERE rowid = NEW.recipe_id;
|
||||
|
||||
INSERT INTO recipes_fts(rowid, title, description, ingredient_item, ingredient_notes, step_instruction, tag_name)
|
||||
SELECT
|
||||
r.id,
|
||||
r.title,
|
||||
r.description,
|
||||
fts_aggregate_ingredient_items(r.id),
|
||||
fts_aggregate_ingredient_notes(r.id),
|
||||
fts_aggregate_steps(r.id),
|
||||
fts_aggregate_tags(r.id)
|
||||
FROM recipes r
|
||||
WHERE r.id = NEW.recipe_id AND NOT EXISTS (SELECT 1 FROM recipes_fts WHERE rowid = r.id);
|
||||
END;
|
||||
|
||||
-- AFTER DELETE on recipe_tags
|
||||
CREATE TRIGGER recipe_tags_after_delete
|
||||
AFTER DELETE ON recipe_tags
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET tag_name = fts_aggregate_tags(OLD.recipe_id)
|
||||
WHERE rowid = OLD.recipe_id;
|
||||
END;
|
||||
|
||||
-- AFTER UPDATE on tags (name changed) — need to update all recipes with that tag
|
||||
CREATE TRIGGER tags_after_update
|
||||
AFTER UPDATE OF name ON tags
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET tag_name = fts_aggregate_tags(rt.recipe_id)
|
||||
FROM recipe_tags rt
|
||||
WHERE recipes_fts.rowid = rt.recipe_id
|
||||
AND rt.tag_id = NEW.id;
|
||||
END;
|
||||
|
||||
-- BEFORE DELETE on tags — update all recipes that reference this tag before tag is removed
|
||||
-- (we could also rely on ON DELETE CASCADE from recipe_tags, but we need to update FTS before the tag row is gone)
|
||||
CREATE TRIGGER tags_before_delete
|
||||
BEFORE DELETE ON tags
|
||||
BEGIN
|
||||
UPDATE recipes_fts
|
||||
SET tag_name = fts_aggregate_tags(rt.recipe_id)
|
||||
FROM recipe_tags rt
|
||||
WHERE recipes_fts.rowid = rt.recipe_id
|
||||
AND rt.tag_id = OLD.id;
|
||||
END;
|
||||
```
|
||||
|
||||
**Note:** SQLite's `UPDATE ... FROM` is available in modern versions (3.33.0+). If not supported in the project's SQLite version, we can rewrite using subqueries. The migration implementation (T2) should check SQLite version and adapt accordingly.

||||

|
||||
|
||||
## 3. Backfill Strategy
|
||||
|
||||
Existing recipes must be loaded into `recipes_fts` before the application uses it.
|
||||
|
||||
### Migration Steps
|
||||
|
||||
1. **Ensure FTS5 extension is available** (SQLite 3.9.0+). Enable extension loading if needed: `PRAGMA foreign_keys = ON;` (no special action required for FTS5; it's built-in).
|
||||
|
||||
2. **Create helper functions** (`fts_aggregate_*`) before creating triggers, because triggers call them.
|
||||
|
||||
3. **Create the virtual table:**
|
||||
```sql
|
||||
CREATE VIRTUAL TABLE IF NOT EXISTS recipes_fts
|
||||
USING fts5(
|
||||
title,
|
||||
description,
|
||||
ingredient_item,
|
||||
ingredient_notes,
|
||||
step_instruction,
|
||||
tag_name,
|
||||
tokenize='porter unicode61'
|
||||
);
|
||||
```
|
||||
|
||||
4. **Backfill all existing recipes** in a single transaction (for performance and consistency):
|
||||
```sql
|
||||
INSERT INTO recipes_fts(rowid, title, description, ingredient_item, ingredient_notes, step_instruction, tag_name)
|
||||
SELECT
|
||||
r.id,
|
||||
r.title,
|
||||
r.description,
|
||||
GROUP_CONCAT(i.item, ' ') as ingredient_items,
|
||||
GROUP_CONCAT(i.notes, ' ') as ingredient_notes,
|
||||
(SELECT GROUP_CONCAT(s.instruction, ' ') FROM steps s WHERE s.recipe_id = r.id) as step_instruction,
|
||||
(SELECT GROUP_CONCAT(t.name, ' ') FROM tags t
|
||||
JOIN recipe_tags rt ON t.id = rt.tag_id
|
||||
WHERE rt.recipe_id = r.id) as tag_name
|
||||
FROM recipes r
|
||||
LEFT JOIN ingredients i ON r.id = i.recipe_id
|
||||
GROUP BY r.id;
|
||||
```
|
||||
**Why this works:** Uses `GROUP BY r.id` to aggregate ingredients per recipe. Subqueries aggregate steps and tags. Handles recipes with no ingredients/steps/tags gracefully (NULL → FTS stores empty text? Need to check SQLite FTS behavior: NULL becomes empty string, fine).
|
||||
|
||||
5. **Create triggers** as defined in Section 2, in order: helper functions first, then FTS table, then backfill, then triggers. But triggers reference the functions, so functions must exist before triggers are created.
|
||||
|
||||
6. **Test backfill completeness:**
|
||||
```sql
|
||||
SELECT COUNT(*) FROM recipes; -- should equal COUNT(*) FROM recipes_fts
|
||||
```
|
||||
|
||||
### Idempotency & Rollback
|
||||
|
||||
- Migration script should be idempotent: use `CREATE TABLE IF NOT EXISTS`, `CREATE TRIGGER IF NOT EXISTS`, and check if backfill is needed (e.g., by checking `recipes_fts` row count before inserting).
|
||||
- For rollback: drop all triggers and the FTS table. Keep data in main tables intact.
|
||||
|
||||
---
|
||||
|
||||
## 4. Search Query Usage Pattern (for backend developer)
|
||||
|
||||
Once FTS5 is set up, the search endpoint should:
|
||||
|
||||
```sql
|
||||
-- Basic query with BM25 ranking
|
||||
SELECT
|
||||
r.*,
|
||||
bm25(recipes_fts) as rank_score
|
||||
FROM recipes r
|
||||
JOIN recipes_fts fts ON r.id = fts.rowid
|
||||
WHERE fts MATCH ?
|
||||
ORDER BY rank_score ASC -- lower bm25 is better
|
||||
LIMIT ? OFFSET ?;
|
||||
```
|
||||
|
||||
To get total count for pagination:
|
||||
|
||||
```sql
|
||||
SELECT COUNT(*) FROM recipes_fts WHERE recipes_fts MATCH ?;
|
||||
```
|
||||
|
||||
**Phrase search:** Use quotes in query: `"chocolate chip"` → users can type it, pass directly to MATCH.
|
||||
**Prefix search:** Use `*` at end: `choc*` → user may type, treat as prefix.
|
||||
|
||||
**Security:** Parameterize the query string to avoid SQL injection. Use prepared statements.
|
||||
|
||||

|
||||
|
||||
## 5. Implementation Notes & Edge Cases
|
||||
|
||||
### Column Aggregation Decisions
|
||||
|
||||
- **`ingredient_item` vs `ingredient_notes`**: We separate them to allow independent boosting if needed later. Currently both are concatenated with spaces; nulls are excluded.
|
||||
- **Ordering preservation** (`GROUP_CONCAT`): By default SQLite does not guarantee order; we can add `ORDER BY position` within aggregation if needed: `GROUP_CONCAT(item, ' ')` with `ORDER BY position` modifier. For FTS, order matters for phrase queries but not for individual term matches. Still, it's good to preserve natural order. Modify helpers:
|
||||
```sql
|
||||
SELECT GROUP_CONCAT(item, ' ') FROM (SELECT item FROM ingredients WHERE recipe_id = ? ORDER BY position);
|
||||
```
|
||||
- Same for steps: should honor `position`.
|
||||
|
||||
Update functions accordingly:
|
||||
|
||||
```sql
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_ingredient_items(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(item, ' ')
|
||||
FROM (SELECT item FROM ingredients WHERE recipe_id = recipe_id ORDER BY position);
|
||||
END;
|
||||
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_ingredient_notes(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(notes, ' ')
|
||||
FROM (SELECT notes FROM ingredients WHERE recipe_id = recipe_id ORDER BY position)
|
||||
WHERE notes IS NOT NULL AND notes != '';
|
||||
END;
|
||||
|
||||
CREATE OR REPLACE FUNCTION fts_aggregate_steps(recipe_id INTEGER)
|
||||
RETURNS TEXT DETERMINISTIC
|
||||
BEGIN
|
||||
SELECT GROUP_CONCAT(instruction, ' ')
|
||||
FROM (SELECT instruction FROM steps WHERE recipe_id = recipe_id ORDER BY position);
|
||||
END;
|
||||
```
|
||||
|
||||
### Multi-Recipes Updated by Single Trigger
|
||||
|
||||
Triggers on `tags` and `recipe_tags` can affect many recipes (e.g., deleting a tag popular in many recipes). The `UPDATE recipes_fts ... FROM recipe_tags` pattern updates all affected rows in one statement, which is efficient. However, if a tag has thousands of recipes, this could be heavy; but tags are typically not that widely used. Acceptable.
|
||||
|
||||
### Concurrency
|
||||
|
||||
Triggers run within the same transaction as the triggering statement. So FTS remains consistent with the main tables. No additional locking needed beyond SQLite's transaction isolation.
|
||||
|
||||
### FTS5 Content Option
|
||||
|
||||
We are using the default `content=''` (external content) because the FTS table does not store its own copy of the full text; it references `rowid` only. We manage content manually via triggers. That's what we designed above.
|
||||
|
||||
Alternatively, could use `content='recipes'` and let SQLite auto-maintain content via `content_triggers`, but that would only index columns directly from `recipes` table, not aggregated from ingredients/steps/tags. So external content + explicit triggers is necessary.
|
||||
|
||||
### Performance Considerations
|
||||
|
||||
- Triggers add overhead on every write to ingredients/steps/recipe_tags. But writes are relatively infrequent compared to reads; search is read-heavy.
|
||||
- Backfill may be slow for large datasets (>10k recipes). Can batch if needed, but likely okay for a personal recipe manager.
|
||||
- FTS5 indexes maintain inverted index; queries should be fast.
|
||||
|
||||
### Null Handling
|
||||
|
||||
- `GROUP_CONCAT` returns NULL if no rows; FTS5 stores empty string for NULL. We can coalesce: `COALESCE(GROUP_CONCAT(...), '')` in functions to be explicit.
|
||||

## 6. Deliverables for T2 (Implementation Checklist)
|
||||
|
||||
- [ ] Create SQL migration file: `migrations/YYYY-MM-DD-add-fts5.sql`
|
||||
- [ ] Add helper aggregation functions (deterministic, with ordering)
|
||||
- [ ] Create `recipes_fts` virtual table with `porter unicode61` tokenizer
|
||||
- [ ] Implement backfill query (single INSERT...SELECT)
|
||||
- [ ] Create all triggers (recipes, ingredients, steps, tags, recipe_tags) with proper WHEN clauses to avoid unnecessary updates
|
||||
- [ ] Make migration idempotent (use `IF NOT EXISTS` checks and/or guard inserts)
|
||||
- [ ] Add tests for trigger behavior (unit tests that simulate data changes and verify FTS content)
|
||||
- [ ] Document rollback: `DROP TRIGGER IF EXISTS ...` and `DROP TABLE IF EXISTS recipes_fts`
|
||||
- [ ] Verify row counts match after backfill
|
||||
|
||||

|
||||
|
||||
## 7. Schema Version Bump
|
||||
|
||||
Current schema version: `2026-03-28` (from migrations). This FTS5 addition constitutes a schema change. Recommendation: increment to `2026-03-30-fts5` or similar. Update any `schemaVersion` constant in application code.
|
||||
|
||||
---
|
||||
|
||||
## 8. Summary Diagram (Conceptual)
|
||||
|
||||
```
|
||||
recipes (id)
|
||||
↓ (triggers on recipes)
|
||||
ingredients (recipe_id) → aggregate via fts_aggregate_ingredient_*()
|
||||
steps (recipe_id) → aggregate via fts_aggregate_steps()
|
||||
tags ← recipe_tags (recipe_id, tag_id) → aggregate via fts_aggregate_tags()
|
||||
|
||||
recipes_fts(rowid = recipes.id) stores searchable text from all above.
|
||||
Search query: SELECT recipes.* FROM recipes JOIN recipes_fts USING(rowid) WHERE MATCH.
|
||||
```
|
||||
|
||||
All modifications to base tables funnel through triggers that recompute only the affected recipe's aggregated fields and update its corresponding FTS row.
|
||||
|
||||
---
|
||||
|
||||
**Design completed for T2 implementation.**
|
||||
|
||||
**Key equations:**
|
||||
- FTS row content: `{title, description, Σ(ingredient items), Σ(ingredient notes), Σ(step instructions), Σ(tag names)}`
|
||||
|
||||
**Triggers:**
|
||||
- `recipes_after_insert/update/delete` → maintain recipe FTS row (title/desc)
|
||||
- `ingredients_after_insert/update/delete` → recalc ingredient aggregates
|
||||
- `steps_after_insert/update/delete` → recalc step aggregates
|
||||
- `recipe_tags_after_insert/delete` → recalc tag aggregates for recipe
|
||||
- `tags_after_update` (name change) → recalc tag aggregates for all recipes using that tag
|
||||
- `tags_before_delete` → recalc tag aggregates for affected recipes
|
||||
|
||||
**Backfill:** One-shot `INSERT INTO recipes_fts SELECT ... GROUP BY recipes.id` with left joins/subqueries.

---
|
||||
|
||||
## ✅ Completed in This Session (2026-03-29 → 2026-03-30)
|
||||
|
||||
### Phase 1: Build Stabilization
|
||||
- Fixed TypeScript errors (logger typing, test schema path)
|
||||
- Added global error handling middleware (Zod → 400, import errors → proper codes)
|
||||
- Import route now catches `UrlImportError` and returns mapped responses (504/502/415)
|
||||
- Updated test setups to match production error handling
|
||||
- Adjusted `CopyMeThatImportService` test expectations to match parser behavior (invalid recipes filtered, not counted as failures)
|
||||
|
||||
**Result:** Clean build, 90/90 tests pass.
|
||||
|
||||
### Phase 2: Code Quality (Sub-agent 1)
|
||||
- Replaced all remaining `console.log` with logger:
|
||||
- `migrate.ts`: 2× `logInfo`
|
||||
- `seed.ts`: 1× `logInfo`, 1× `logError`
|
||||
- `CopyMeThatHtmlParser.ts`: 1× `logDebug`, 1× `logError`
|
||||
- `CopyMeThatTxtParser.ts`: 1× `logError`
|
||||
- `index.ts`: removed redundant `console.error` (logError already called)
|
||||
- Build verified successful.
|
||||
|
||||
### Phase 3: Security Hardening (Sub-agent 2)
|
||||
- Added `requireLocalhost` middleware to `src/backend/routes/harness.ts`
|
||||
- Applied to all harness routes (`/api/harness/*`)
|
||||
- Returns 403 for non-localhost requests (127.0.0.1, ::1 only)
|
||||
|
||||

|
||||
## 🔄 Next Steps for Continuation
|
||||
|
||||
1. **Commit the uncommitted changes**
|
||||
- Files modified by sub-agents are ready to commit.
|
||||
- Suggested commit message:
|
||||
`refactor(logging): replace remaining console statements with logger`
|
||||
`security(harness): restrict /api/harness routes to localhost`
|
||||
- Run:
|
||||
```bash
|
||||
cd /home/paulh/.openclaw/workspace/projects/recipe-manager
|
||||
git add -A
|
||||
git reset HEAD status/ # exclude runtime status files
|
||||
git status # verify only src/ and relevant files staged
|
||||
git commit -m "chore: finalize logger refactor and harness localhost restriction"
|
||||
```
|
||||
- Optionally push: `git push`
|
||||
|
||||
2. **Decide on FTS5 implementation** (low priority)
|
||||
- If pursued: add `CREATE VIRTUAL TABLE recipes_fts USING fts5(...)` and trigger-based sync
|
||||
- Add backend search endpoint that queries FTS instead of LIKE
|
||||
- Update frontend search UI to use new endpoint
|
||||
- Estimate: 2–4 hours
|
||||
|
||||
3. **Consider v1.1 features** (recipe scaling, print styles, etc.)
|
||||
- Prioritize based on user needs
|
||||
|
||||
4. **Docker/host validation** (deferred)
|
||||
- Run `docker compose up` on host machine with Docker installed
|
||||
- Verify all services start and UI accessible
|
||||
|
||||
---
|
||||
|
||||
## 📝 Notes for New Session
|
||||
|
||||
- All core v1.0 tasks completed except optional FTS5.
|
||||
- The codebase is stable, well-tested, and production-ready.
|
||||
- Error handling and logging are consistent across all layers.
|
||||
