"""Pipeline Step 15 (BM25 + 세트) — 개별 토큰 + 복합 토큰(세트) 모두 넣은 BM25.
이전 pipeline_15_bm25_comparison 은 개별 토큰만 썼음 → 세트 정보 누락.
이번엔 세트를 "복합 토큰(phrase token)" 으로 취급해 BM25 에 포함.
복합 토큰 정의:
· 프레임의 각 source_text_line 에서 추출된 키워드 묶음 (예: [BIM, DX, 이해])
· tf(compound, frame) = 1 (한 source line = 1 occurrence)
· df(compound) = "그 모든 키워드를 다 가진 프레임 수"
· IDF(compound) = log((N - df + 0.5) / (df + 0.5) + 1)
복합 토큰 매칭 (MDX 쪽):
· MDX 에 compound 의 키워드가 얼마나 있나 → coverage (0~1)
· 기여도 = IDF(compound) × tf_norm × coverage (부분 매칭 허용)
최종 BM25 점수 = Σ 개별 토큰 기여 + Σ 복합 토큰 기여
