Hybrid Retrieval for RAG

Combine vector similarity with keyword matching for superior retrieval accuracy.

Why Hybrid is Mandatory in 2026

Vector search alone misses:

• Exact matches (product codes, IDs, names)
• Rare terms not well-represented in embeddings
• Keyword-specific queries ("error code E-5012")

Keyword search alone misses:

• Semantic similarity ("car" vs "automobile")
• Context and meaning
• Paraphrased content

Hybrid search combines both for 15-25% better recall.
