⚡ Bolt: [세트 교집합 최적화를 통한 성능 향상]

[seonghobae]

💡 What: transcript_search.py에서 불필요한 set() 복사본 생성을 제거하고 설명을 위한 주석을 추가했습니다.
🎯 Why: & 연산자는 항상 새로운 세트를 반환하므로, 초기 방어적 복사본 생성은 불필요한 O(N) 할당을 유발하여 성능 병목 현상을 일으킵니다.
📊 Impact: 세트 할당 오버헤드를 제거하여 대규모 트랜스크립트 검색 성능을 향상시킵니다.
🔬 Measurement: 검색 쿼리에 여러 조건이 포함된 경우의 응답 시간을 프로파일링하여 확인할 수 있습니다.

📝 Walkthrough

Walkthrough

TranscriptIndex.search는 첫 검색어의 posting set을 복사하지 않고 직접 사용합니다. 이후 검색어에는 기존과 같이 교집합 연산을 적용합니다. 관련 최적화 원칙을 학습 노트에 추가했습니다.

Changes

검색 후보 집합 최적화

Layer / File(s)	Summary
후보 집합 초기화 변경 transcript_search.py, .jules/bolt.md	첫 검색어 처리에서 set(postings) 복사를 제거했습니다. 후속 검색어의 교집합 계산은 유지했습니다. 변경 원칙을 학습 노트에 기록했습니다.

Estimated code review effort: 1 (매우 낮음) | ~5분

Merge Risk: ⚪ Minimal · up to 8a59a

Transcript search avoids copying the initial posting set while preserving intersection behavior, reducing allocation on multi-condition searches with no remaining merge-blocking risk.
