* fix(bm25): return FTS-matched symbols instead of arbitrary LIMIT 3 nodes Previously, bm25Search fetched up to 3 arbitrary symbols from the matched file using MATCH (n) WHERE n.filePath = $filePath LIMIT 3 (no ORDER BY). This meant the specific function or class that actually scored highest in the BM25 index could be completely absent from the results. Fix: propagate nodeId from each FTS hit through searchFTSFromLbug, then use those nodeIds in bm25Search to look up the exact matched nodes via WHERE n.id IN $nodeIds. Falls back to the old filePath-based lookup when nodeIds are unavailable. Also switches the per-file score aggregation from naive sum-of-all to sum-of-top-3, which prevents files with many mediocre matches (e.g. test files) from outranking files with a single highly-relevant symbol. * test(bm25): add unit tests for top-3 aggregation and nodeIds propagation Covers the new logic paths added in the previous commit: - top-3 score aggregation (file with 5+ matches → only top-3 contribute) - nodeIds propagation through BM25SearchResult - empty nodeId filtering - cross-table merge for the same file - result ranking by aggregated score Also fixes in-place entries.sort() mutation (bm25-index.ts:125) to use [...entries].sort() so the Map value is not silently modified. * style: apply prettier formatting * fix(test): use importOriginal to avoid missing export errors in vi.mock * fix(bm25): align queryFTSViaExecutor nodeId extraction to match lbug-adapter Use node.nodeId || node.id || '' in queryFTSViaExecutor to match the fallback logic in lbug-adapter.ts:1040. Without this, the MCP pool path could silently return empty nodeIds if LadybugDB surfaces the node id under node.nodeId rather than node.id. --------- Co-authored-by: jisue0224 <> |
