🔍 Search Relevance Lab

Fusion comparison

The core question: does hybrid retrieval (combining lexical + vector) beat either backend alone? The cards show each approach's average nDCG; the table is one row per query, with all three scores and a category summarising how hybrid did. Sorted so hybrid's biggest wins are at the top. Use the filters to isolate where fusion helped vs. hurt.

What do the categories mean?
beat_both
Hybrid scored higher than both lexical and vector — fusion helped.
lost_both
Hybrid scored lower than both — fusion hurt.
between
Hybrid landed between the two single backends.
tied
Hybrid matched both (often a query where neither found anything).
