Module search 

WARP search algorithm components

This module implements the three phases of WARP search:

1. Centroid Selection - For each query token, find top-nprobe centroids
2. Candidate Scoring - Decompress and score tokens from selected centroids
3. Score Merging - Aggregate per-token scores into document scores via MaxSim

Structs

CandidateScorer

Phase 2: Score candidates from a centroid.

CentroidSelector

Phase 1: Select top centroids per query token.

ScoreMerger

Phase 3: Merge per-token scores into document scores via MaxSim.

Functions

exact_maxsim

Compute exact MaxSim score (for testing/comparison).
