# Phase 5 Plan 3: Search Integration Summary

**Full search and filter integration with recent searches, text highlighting, and flat list mode**

## Performance

- **Duration:** 4 min
- **Started:** 2026-01-31T16:16:26Z
- **Completed:** 2026-01-31T16:20:30Z
- **Tasks:** 3
- **Files modified:** 6

## Accomplishments

- Created recentSearches store with persistence and 5-item deduplication
- Integrated SearchBar dropdown showing recent searches on focus
- Added reactive filtering in EntryList with flat list mode when filtering
- Implemented text highlighting in EntryCard collapsed view
- Wired complete search UI in +page.svelte with state synchronization

## Task Commits

Each task was committed atomically:

1. **Task 1: Create recent searches store and add dropdown UI** - `af61b10` (feat)
2. **Task 2: Integrate filtering into EntryList with flat list mode** - `9642b51` (feat)
3. **Task 3: Add highlighting to EntryCard and integrate search UI** - `bb1e64a` (feat)

## Files Created/Modified

- `src/lib/stores/recentSearches.ts` - Persisted store for recent searches with addRecentSearch function
- `src/lib/components/SearchBar.svelte` - Added recent searches dropdown, focus/blur handlers
- `src/lib/components/EntryList.svelte` - Added filters/searchQuery props, flat list mode, search empty state
- `src/lib/components/EntryCard.svelte` - Added searchQuery prop, {@html highlightText()} for title/content
- `src/routes/+page.svelte` - Integrated SearchBar, FilterBar, state management
- `src/lib/utils/filterEntries.ts` - Made generic to preserve entry type

## Decisions Made

1. **Recent searches on blur:** Save to recent searches when input loses focus with >= 2 chars, avoiding double-saves
2. **onmousedown for selection:** Use onmousedown instead of onclick for dropdown items to fire before onblur
3. **Generic filterEntries:** Changed to `filterEntries<T extends EntryWithTags>` to preserve full entry type including images field
4. **Highlight in collapsed only:** Apply highlighting only in collapsed view where preview text is shown

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Fixed filterEntries type to preserve images field**
- **Found during:** Task 3 (type check after page integration)
- **Issue:** filterEntries returned EntryWithTags which lacks images, but EntryCard requires images
- **Fix:** Made filterEntries generic with `<T extends EntryWithTags>` to preserve full type
- **Files modified:** src/lib/utils/filterEntries.ts
- **Verification:** npm run check passes with 0 errors
- **Committed in:** bb1e64a (Task 3 commit)

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** Minor type fix necessary for TypeScript compatibility. No scope creep.

## Issues Encountered

None - plan executed smoothly.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Search and filter fully functional
- Phase 5 complete, ready for Phase 6 (Polish)
- All must_haves verified:
  - User can search entries by typing
  - User can filter by type, tags, date range
  - Matching text highlighted with bold
  - Pinned entries in flat list during search
  - Empty state shows friendly message
  - "/" key focuses search
  - Recent searches appear as quick picks
  - Clear button resets filters
