FAQPage Schema
How do I build a RAG pipeline with a self-hosted vector database?

You can build a RAG pipeline using a self-hosted vector database by storing text embeddings and metadata, then querying them for fast semantic search and document retrieval without vendor lock-in.

What is an open-source embedding database used for?

An open-source embedding database is used to store and query embeddings and metadata, enabling fast similarity search, semantic retrieval, and scalable private AI workflows across notebooks and production deployments.

Does ChromaDB support metadata filtering for semantic search?

Yes, ChromaDB supports metadata filtering, allowing you to store documents with metadata and run filtered similarity queries to refine semantic search and document retrieval results.

Can I use a vector store for production-grade AI apps and notebook prototyping?

Yes, this vector store provides a simple API designed for both notebook prototyping and production-grade deployments, enabling flexible vector storage and full-text search over embeddings and metadata.

What is the best way to avoid vendor lock-in when storing text embeddings?

The best way to avoid vendor lock-in is using an open-source, self-hosted embedding database, which provides scalable storage and similarity search while keeping your AI workflows and data entirely private.

Do I need to install any dependencies to run an open-source vector store?

Yes, you need to install the chromadb library and set up a client to create collections, add documents with metadata, and execute similarity queries for your semantic search applications.
