FAQPage Schema
How do I perform local vector search for a RAG pipeline without using cloud services?

Local vector search for a RAG pipeline is achieved by storing embeddings and associated metadata on your own device. This self-hosted approach enables fast vector lookup and privacy without relying on external cloud services.

What is the best way to store embeddings locally for on-device document retrieval?

Storing embeddings locally for on-device document retrieval requires initializing a self-hosted vector store client. You can create collections to store embeddings and perform fast semantic search queries across your documents.

Can I filter vector search results using metadata in a local vector database?

Filtering vector search results by metadata is fully supported in this local vector database. You can apply metadata filters to narrow down vector and text-based queries for more precise document retrieval.

Does a self-hosted vector store work for both notebook prototyping and production deployments?

A self-hosted vector store works across both notebook prototyping and production server deployments. It provides a simple API for storing and querying embeddings that scales from on-device AI testing to live applications.

Are there limitations to building privacy-preserving RAG systems with a local vector store?

Building privacy-preserving RAG systems with a local vector store requires managing your own storage infrastructure. While it ensures data privacy, you must handle the embedding generation pipeline and local server maintenance yourself.
