FAQPage Schema
How do I store and query embeddings locally for semantic search?

Store and query embeddings locally by creating a collection, adding documents with metadata, and running similarity searches. This self-hosted embedding database enables fast retrieval with vector and text search without external API dependencies.

What is metadata filtering in a vector database and when do I need it?

Metadata filtering in a vector database narrows retrieval results by applying attribute conditions alongside vector similarity. You need it when building RAG pipelines or document retrieval systems requiring targeted searches across specific document categories or tags.

Can I use a self-hosted embedding database with LangChain or LlamaIndex?

Yes, this self-hosted embedding database supports framework integrations with LangChain and LlamaIndex. You can connect it directly within your existing RAG pipelines to manage vector storage and retrieval locally.

How do I set up a local vector database for a RAG pipeline?

Install the chromadb package, create a collection, add your documents with metadata, and execute a basic similarity search. This provides a local vector database ready for RAG pipeline integration and document retrieval.

Is a self-hosted vector database suitable for light production deployments?

Yes, this self-hosted vector database is suitable for notebooks, experiments, and light production deployments. It offers a simple four-function API for vector storage and retrieval while maintaining privacy-preserving local data control.

Does this semantic search tool support full-text search alongside vector retrieval?

Yes, the semantic search tool supports both full-text search and vector retrieval capabilities. You can apply metadata filtering to both search methods to enable efficient AI retrieval across your stored documents.
