FAQPage Schema
How do I store and retrieve embeddings for semantic search in local development?

Store and retrieve embeddings with metadata using an open-source vector database. You can apply it to local development, notebooks, and production deployments for fast similarity search and document retrieval.

What is an open-source vector database used for in RAG pipelines?

An open-source vector database is used for storing high-dimensional embeddings and metadata in RAG pipelines. It enables fast similarity search and scalable memory across AI applications.

How do I filter document retrieval results by metadata in a vector store?

Filter document retrieval results by metadata using a simple 4-function API. The vector store supports vector and full-text search alongside metadata filtering to narrow down retrieved documents.

Can I use an open-source vector database for both local notebooks and production deployments?

Yes, you can use this open-source vector database for local notebooks and production deployments. It supports persistent storage to maintain your embeddings and metadata across different environments.

Does this vector store support full-text search alongside semantic vector search?

Yes, the vector store supports both full-text search and semantic vector search. You can perform either search method and apply metadata filtering to refine the retrieved results.
