README

This package provides an implementation of multiple vector databases (e.g. Pinecone.io).

If this helped you, consider supporting my development over on Patreon or on Github.

Installation

Requires PHP ^8.1

composer require adrianmtanase/laravel-vector-store

Currently supports

• Pinecone.io
• Weaviate

Plans to implement

• MySql - once it's ready

❗ If you're coming from version 0.0.25 ❗

• Coming from version 0.0.25 you'll have to re-publish the config, as the Pinecone environment variable has been replaced with pinecone_host

php artisan vendor:publish

Usage

Using the VectorStore facade, you can easily access any provider and execute operations.

VectorStore::instance()
           ->namespace('general')
           ->upsert(
               PineconeUpsertRequest::build()
                   ->id('1')
                   ->values([
                       -0.002739503,
                       -0.01970483,
                       -0.011307885,
                       -0.011125952,
                       -0.023119587,
                       0.0016207852,
                       -0.003981551,
                       -0.029249357,
                       0.00983842,
                       -0.023721369
                   ])
                   ->metadata([
                       'text' => 'Vector store is lit!'
                   ])
           );

The default provider is Pinecone.io, this can be easily switched using the facade VectorStore::provider(VectorStoreProviderType::PINECONE), or directly in the vector-store config.

Weaviate

As Weaviate runs through GraphQL, the query language is complex. There are several useful methods in WeaviateQueryRequest that will help you query data more efficiently. For example:

VectorStore::provider(VectorStoreProviderType::WEAVIATE)
           ->instance()
           ->namespace('general')
           ->query(
               WeaviateQueryRequest::build()
                   ->vector([
                       -0.002739503,
                       -0.01970483,
                       -0.011307885,
                       -0.011125952,
                       -0.023119587,
                       0.0016207852,
                       -0.003981551,
                       -0.029249357,
                       0.00983842,
                       -0.023721369
                   ])
                   ->properties(['text'])
                   ->withId()
                   ->withParameters(WeaviateQueryParameters::build()->group('type: closest, force: 1'))
           );

As the system is complex, the package also supports a rawQuery form, or even getting access to the underlying client.

Weaviate raw query

VectorStore::provider(VectorStoreProviderType::WEAVIATE)
           ->instance()
           ->namespace('general')
           ->rawQuery('
               {
                Get {
                  General(nearVector: {
                    vector: [
                        -0.002739503,
                       -0.01970483,
                       -0.011307885,
                       -0.011125952,
                       -0.023119587,
                       0.0016207852,
                       -0.003981551,
                       -0.029249357,
                       0.00983842,
                       -0.023721369
                    ]  
                  }) {
                    text
                  }
                }
            }
           ');

Underlying Weaviate client

VectorStore::provider(VectorStoreProviderType::WEAVIATE)
           ->instance()
           ->client()
           ->batchDelete('general')
