| ## 2026-11-20 - [Fast O(1) Path Property Early-Exit] | ||
| **Learning:** Checking `itemBitflags` (which aggregates `name`, `fullName`, and `path`) is an effective early exit for overall matches. However, when falling back to `tryFuzzyMatchPath`, the evaluation proceeds directly to expensive `Fuzzysort.single()` string operations on the path. If the characters were matched from the `name` or `fullName`, but not the path, missing an explicit `path` bitflag check results in wasted fuzzy search cycles. | ||
| **Action:** Isolate and maintain an `itemPathBitflags` array in hot paths, parallel to `itemNameBitflags` and `itemFullNameBitflags`. Use this specific bitmask to implement an O(1) early-exit check inside `tryFuzzyMatchPath` before executing expensive string evaluations. |

Use a non-future date or mark this as planned. This entry is dated 2026-11-20, which makes the log chronology misleading. If it’s planned content, label it as such; otherwise change it to the actual entry date.

💡 What
Introduces a new parallel array
itemPathBitflagsto theSearchEngine.Adds an O(1) early-exit bitmask check inside
tryFuzzyMatchPath.🎯 Why
Currently, if an item passes the aggregate
itemBitflagscheck, it proceeds to thetryFuzzyMatchPathfallback if earlier name and full name scores aren't sufficient. Without a specific bitflag for the path,tryFuzzyMatchPathunconditionally runs an expensiveFuzzysort.single()operation on the file path, even if the required characters for the match were only present in thenameorfullName, leading to wasted CPU cycles in exhaustive searches.📊 Impact
Significantly reduces the number of
Fuzzysort.single()invocations during fallback path evaluations. For items where the match characters are distributed strictly outside the path property, thetryFuzzyMatchPathcall resolves in O(1) time (~0.01ms) instead of evaluating a lengthy string.🔬 Measurement
Run
cd language-server && bun test. Execution paths for missing characters should hit the early-exit conditional intryFuzzyMatchPathinstead of proceeding toFuzzysort.single().PR created automatically by Jules for task 8830878369743954837 started by @AhmmedSamier
