SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Hybrid search addresses the challenge of retrieval systems missing relevant results when relying solely on vector similarity or keyword matching. By combining both approaches, it improves recall for diverse queries and domain vocabularies.

Core Features & Use Cases

  • Hybrid retrieval architecture that fuses vector similarity with keyword matching for more robust results.
  • Supports multiple fusion strategies (RRF, Linear, Cross-encoder, Cascade) and optional reranking for quality control.
  • Use cases include building RAG pipelines, search engines, and any domain requiring both semantic understanding and exact-term matches.

Quick Start

Provide a query and its embedding to perform a hybrid search and retrieve the top matching documents.

FAQPage Schema
What is hybrid search and when do I need it for my RAG pipeline?▼

Hybrid search combines vector similarity and keyword matching to improve recall in retrieval systems. You need it when your RAG pipeline misses relevant results by relying solely on semantic understanding or exact-term matching.

How do I combine vector similarity and keyword matching to improve search recall?▼

You can combine vector similarity and keyword matching by applying fusion strategies like Reciprocal Rank Fusion (RRF), Linear, Cross-encoder, or Cascade. This architecture fuses both retrieval methods to deliver more robust results.

What fusion methods are available for merging vector and keyword search results?▼

Available fusion methods for merging vector and keyword search results include Reciprocal Rank Fusion (RRF), Linear fusion, Cross-encoder, and Cascade. Optional reranking can also be applied for additional quality control.

Does hybrid search work with existing vector stores and text indexes?▼

Yes, hybrid search can integrate directly with existing vector stores and text indexes. This allows you to fuse vector similarity and keyword matching without completely replacing your current retrieval infrastructure.

Why does my vector search miss relevant documents with specific domain vocabulary?▼

Vector search misses relevant documents because it lacks exact-term matching for specific domain vocabulary. Hybrid search solves this by fusing vector similarity with keyword matching to capture both semantic understanding and exact terms.
