We've added an optional cross-encoder reranking stage to our hybrid search pipeline, using Claude Haiku to refine the sorting of top-N search candidates. The implementation includes robust graceful degradation, ensuring that the original RRF-fused order is preserved if the reranking call fails or if an API key is missing. This update enhances retrieval precision while maintaining search reliability. Improve search relevance
