Efficient RAG Index Updates for Dynamic Docs

By PulseAugur Editorial · [1 sources] ·

This article details a method for efficiently updating Retrieval-Augmented Generation (RAG) indexes with changing documentation sites. Instead of a full re-crawl and re-embedding, it proposes a system that identifies only the modified, added, or deleted content chunks. This approach leverages a tool called Website Change Tracker, which analyzes website changes and provides specific lists of chunks to upsert and delete. The updated chunks are then applied to vector stores like Chroma, Qdrant, Pinecone, Weaviate, or pgvector, ensuring the RAG index remains synchronized with the live documentation. AI

IMPACT Enables more up-to-date and accurate RAG systems by efficiently syncing with dynamic documentation.

    Keep a RAG index in sync with a docs site by re-embedding only the chunks that changed

    <p>A support bot or internal assistant built on a documentation site goes stale the week after launch. The docs change, the vector index doesn't, and the bot keeps quoting the old pricing page. The usual fix is a nightly full re-crawl and re-embed, which pays to embed thousands o…
