- Index notes in a separate, rebuildable SQLite database (index.db) using FTS5 trigram, synced from watcher snapshots so external edits are picked up; terms under 3 characters fall back to LIKE - GET /api/v1/search?q= returns matching notes with the first matching line and a snippet; path matches rank first - Sidebar search panel (Ctrl+Shift+F) with highlighted terms and keyboard navigation; opening a result jumps to and selects the match - Restore scroll position on tab switch with scroll snapshots; restoring scrollTop drifted by a few lines after line heights were re-estimated
