What is hybrid search?

Hybrid search combines semantic vector search with traditional keyword search (like BM25) to provide better results than either method alone.

How does re-ranking improve search results?

Re-ranking uses a cross-encoder model to evaluate the top candidates from the initial search more deeply, significantly increasing the precision of the final results.

Does this skill support PostgreSQL?

Yes, it includes specific templates for pgvector and full-text search integration using PostgreSQL to perform high-performance hybrid queries.

When should I use RRF over linear weights?

Use RRF (Reciprocal Rank Fusion) when your search methods produce scores on different scales; use linear weighting when you need precise control over the influence of each method.

データサイエンスとML

Combines vector similarity and keyword-based search to optimize retrieval accuracy and recall in RAG systems and search engines.

This skill provides standardized patterns and implementation templates for hybrid search, bridging the gap between semantic understanding and exact keyword matching. It includes robust configurations for Reciprocal Rank Fusion (RRF), linear scoring, and advanced re-ranking using cross-encoders. Designed for developers building LLM applications, it offers ready-to-use code for PostgreSQL (pgvector), Elasticsearch, and Python-based fusion logic, ensuring high-quality document retrieval even when domain-specific terminology or precise identifiers are required.
