Uses max FTS score as baseline for exact name matches to ensure nameMatchBonus differentiation during rescoring, increases exact match limit from 5 to 20 candidates, and adds common conversational terms to stop words to reduce query noise.
Expands symbol lookup with morphological variants (e.g., "caching"→"cache", "eviction"→"evict") to find related class definitions that FTS prefix matching would otherwise miss. Includes comprehensive stemming rules for common English suffixes (-ing, -tion, -ed, -er, etc.) and integrates stem expansion into definition prefix search for improved symbol discovery.
Adds nameMatchBonus scoring to prioritize results where node names exactly or partially match query terms. Implements dedicated field extraction for Java/C# to properly categorize class fields vs variables. Optimizes BM25 search with column weights favoring name matches and increased result fetching before post-processing. Refines stop words list to preserve common programming terms like "get", "find", "list".
Improves search accuracy by boosting results when multiple query symbols appear in the same file, addressing cases where common names like "run" return too many results. Adds Go method receiver type extraction to qualified names for better searchability (e.g., "scrapeLoop.run"). Optimizes database queries with two-pass approach to handle distinctive vs common symbol names efficiently.
Eliminate cross-language false positives in name resolution and deprioritize
test files in context building. Benchmarked on a Python+Rust codebase where
37% of edges were false positives from Python built-in methods resolving to
Rust functions (e.g., list.extend → Rust extend).
Resolution fixes (index-time):
- Filter Python built-in type method calls (list.extend, dict.update, etc.)
- Filter bare Python built-in method names (append, extend, pop, keys, etc.)
- Add language boundary checks to matchMethodCall strategies 1, 2, and 3
- Penalize cross-language matches: -80 points in findBestMatch (was 0)
- Reduce confidence for single cross-language exact matches (0.5 vs 0.9)
- Prefer same-language candidates in matchFuzzy
Context relevance fixes (query-time):
- Add isTestFile() utility detecting test files across Python/JS/TS/Go/Rust/Java
- Deprioritize test files in scorePathRelevance (-15 penalty)
- Reduce test file scores to 30% in context builder result merging
- Both skip deprioritization when query mentions "test" or "spec"

extractSearchTerms now splits camelCase, PascalCase, snake_case, and
dot.notation into individual tokens (e.g. "getUserName" → ["user", "name"]).
Stop words expanded with code-specific noise words (code, file, function,
method, class, type, etc.) to improve search precision.

Both functions have zero callers — dead code on arrival. Remove them
and their tests (9 tests) to keep the module focused on what's
actually used: search term extraction, path relevance scoring, and
kind bonuses.
