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

You can store embeddings locally for semantic search by deploying a self-hosted vector database that handles storage and similarity queries. This Skill provides local vector storage with metadata filtering, supporting low-latency access and offline development.

Can I use a local vector database with LangChain or LlamaIndex?

Yes, local vector databases integrate with LangChain and LlamaIndex for RAG pipelines. This Skill supports seamless retrieval and reasoning workflows within these AI tooling frameworks, enabling document retrieval and memory-intensive AI tasks.

What's the best way to filter metadata in vector retrieval for RAG pipelines?

The best way to filter metadata in vector retrieval is using a database that supports metadata filtering alongside similarity search. This Skill enables robust filtering across multiple collections to support RAG pipelines and document retrieval tasks.

Do I need an external server to run a vector database for AI memory?

No, you do not need an external server. This Skill provides a local, self-hosted vector database for privacy and offline development. You can initialize a collection and begin storing embeddings directly after installation.

How does a local vector database handle similarity search?

A local vector database handles similarity search by comparing stored embeddings against query vectors. This Skill adheres to a simple 4-function API for creating, adding, querying, and managing collections to deliver fast similarity search results.

When do I need a local vector database for AI workflows?

You need a local vector database for AI workflows requiring privacy, low-latency access, or offline development. It is applicable for memory-intensive AI tasks, RAG pipelines, and document retrieval that require fast similarity search and robust filtering.
