Rewrite SearchService.searchPage into ONE engine for web-UI, MCP agent and
share:
- A2 server-side query parser (search-query-parser.ts): quote-aware
tokenizer, leading +/- operators (internal -,.,: literal), "phrase",
metachar-stripped bare terms; tsquery built as a parameterized AST via
SQL ||/&&/!! (never string-concat). only-negation/empty short-circuit.
- A3 match=auto routes identifier-like terms (10.31.41, esp32,
WB-MGE-30D86B) to the substring/trigram branch, words to FTS; word/
prefix/substring overrides.
- A4 RRF (k=60) fuses the FTS branch (ts_rank_cd) and substring branch
(title-exact>title-sub>text tier) by RANK; ORDER BY rrf DESC, id.
- A5 exact permission-filtered total (fail-closed via filterAccessiblePageIds
with the #348 hasRestricted fast-path), CANDIDATE_CAP fusion window,
offset/limit, hasMore, truncatedAtCap.
- A6 single path (spaceId/share/creatorId/titleOnly/parentPageId/match);
share uses getPageAndDescendantsExcludingRestricted.
- A7 response superset per hit (id/pageId/slugId/icon/title/space/…/rank/
highlight/snippet/path/score/matchedFields/matchedTerms).
- A8 buildAncestorPaths now skips deleted + cross-space ancestors.
- A9 DTOs: match, offset, total/hasMore/truncatedAtCap/query/matchedFields.
SEARCH_MODE=or|and toggles the parser; SEARCH_CANDIDATE_CAP tunes the
window. Legacy lookup unit/int specs replaced by parser unit tests + a
13-criteria integration spec on real pg (incl. a permission mutation guard
and a fail-closed propagation test).
