Rank interleaving guarantees every database slots regardless of content; on domain-split collections it allocates no better than chance and costs 4.7pp recall@5 at four collections against score ordering (7.1pp at eight). Hybrid scores are each database's own vector/FTS rank agreement, which carries across databases; equal scores resolve by within-database rank, and only a tie on both falls to configured order, leaving permutation sensitivity at 0.02-0.26pp. Fused results carry the candidate's own retrieval score, so the context-expansion re-sort preserves fused order. |
