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.
