Retail Search - Phase 1 explain

Explain

This project evolves one search system through validated architecture milestones. Run the same query through each milestone and watch how the retrieval flow, ranking evidence, and results change as the architecture evolves.

JSON

Run explain across architectures

Compare all milestones side by side or focus on one. ARCH-0.1 ranks with plain BM25, ARCH-0.2 PRF reranks the same candidate pool with pseudo-relevance feedback, and ARCH-0.3 BGE reports its validated remote evidence because live vector runtime is not enabled yet.

Run explain to see how each architecture milestone processes the same query.

Milestone JSON endpoints

The same comparison is available as raw JSON from the stable milestone endpoints.
