Vector Store Plugins¶

A vector store plugin is a Python package for a specific vector store implementation. All vector store plugins can be used to store and search embeddings via the unified CLI interface.

embcli-chroma for ChromaDB¶

The embcli-chroma plugin provides ChromaDB integration.

Installation: pip install embcli-chroma

emb vector-stores command shows the available vector stores with their short aliaases.

emb vector-stores
ChromaVectorStore
    Vendor: chroma
LanceDBVectorStore
    Vendor: lancedb

Example usage: store and search embeddings in ChromaDB.

We assume you have installed the embcli-sbert plugin to generate embeddings.

# index example documents to a Chroma collection. Default chroma db path is `./chroma`.
emb ingest-sample -m sbert -c catcafe --corpus cat-names-en --vector-store chroma

# or, you can give the path to your db path.
emb ingest-sample -m sbert -c catcafe --corpus cat-names-en --vector-store chroma --persist-path /path/to/chroma

# search indexed documents in a Chroma collection.
emb search -m sbert -c catcafe -q "Who's the naughtiest one?" --vector-store chroma

# or, you can give the path to your db path.
emb search -m sbert -c catcafe -q "Who's the naughtiest one?" --vector-store chroma --persist-path /path/to/chroma
