Snider	fc758a832b	feat(search): add English stemmer for improved search recall ... Implement lightweight Porter-style suffix stripping in stemmer.go covering plurals (-sses, -ies, -s), verb forms (-ed, -ing, -eed), and derivational suffixes (-ational, -tional, -fulness, -ness, -ment, -ation, -ously, -ively, -ably, -ally, -izer, -ingly). Words under 4 chars are unchanged and results are guaranteed at least 2 chars. tokenize() now emits both raw and stemmed forms so the index contains both. Search() distinguishes stem-only matches (scoreStemWord=0.7) from exact matches (1.0), keeping stemmed results slightly below raw hits. 22 stem unit tests, 5 search integration tests, and BenchmarkStem with 100 words. All existing tests pass with no regressions. Co-Authored-By: Virgil <virgil@lethean.io> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-20 08:07:50 +00:00
