FTS5 design spec revision complete. Here’s a summary of all changes made:
Revision Summary — FTS5 Design Spec v2
HIGH (1)
- FTS5 MATCH query syntax injection — Added complete
escapeFts5Query()function (Section 4.2) with detailed JSDoc, examples, and trade-off notes. The function strips double quotes, splits on whitespace, and wraps each token in quotes to neutralize FTS5 operators. Applied insearchReports()before MATCH.
MEDIUM (4)
- MCP handler try-catch — Section 4.1 now wraps the entire handler in try-catch, consistent with
soul_read/soul_writepatterns. Returns{ isError: true }on failure. - Migration rollback SQL — Added Section 3.4 with complete rollback: DROP 3 triggers + DROP virtual table + PRAGMA user_version reset.
- MCP handler formatting — Replaced
// ... format and returnwith complete formatting logic: numbered results with score, snippets, trace, and optional full_result. Empty results return a helpful message. - LIKE fallback performance — Added Section 6.4 with quantified analysis: ~5,000 rows × ~2.2 KB = ~11 MB scan → 15-25 ms. Acceptable for rare edge case. Includes scaling guidance.
LOW (4)
fullparam in shortQueryFallback — Now destructuresfulland conditionally addsresult AS full_resultto the LIKE query.- Database type import — Changed to
import type Database from 'better-sqlite3'and parameter type toDatabase.Database. - NULL LIKE semantics — Added inline comment explaining
NULL LIKE '%x%'→ NULL behavior. AddedCOALESCEfor SUBSTR snippets to prevent null output. - Snippet tokens for CJK — Increased from 10/20 to 16/32 tokens. Documented rationale: trigram tokens average ~1 char for CJK.
