README

A Laravel-friendly wrapper for the Qdrant vector database. This package allows you to interact with Qdrant API easily using a Laravel-style API.

Requirements

• PHP ^8.2
• Guzzle ^7.8.0 (version 7.9.3 installed)
• Symfony UID ^7.3

Installation

composer require vinothkumar/laravel-qdrant

For modern Laravel versions (5.5+), the service provider and facade are auto-discovered. You typically do not need to manually add them to your config/app.php.

Configuration

Publish the config file:

php artisan vendor:publish --provider="Vinothkumar\Qdrant\QdrantServiceProvider" --tag="config"

This will publish a qdrant.php file to your config directory. Set your Qdrant configuration in your .env file:

QDRANT_HOST=http://localhost:6333
QDRANT_API_KEY=your_api_key_here
QDRANT_TIMEOUT=30

Available configuration options:

• host: The URL of your Qdrant instance (e.g., http://localhost:6333).
• api_key: Your Qdrant API key, if required (optional, defaults to null).
• timeout: Request timeout in seconds for Guzzle client (optional, defaults to 10).

Usage

You can use the Qdrant facade or inject the Vinothkumar\Qdrant\Services\QdrantService class where needed.

Collection Management

// Create a collection
Qdrant::createCollection('products', [
    'size' => 1536,
    'distance' => 'Cosine'
]);

// Get collection info
$info = Qdrant::getCollection('products');

// List all collections
$collections = Qdrant::listCollections();

// Delete a collection
Qdrant::deleteCollection('products');

Points Management

// Insert a single point
Qdrant::insert('products', 'product-123', [0.23, 0.44, 0.98], [
    'name' => 'Product Name',
    'category' => 'Electronics'
]);

// Batch insert multiple points
$points = [
    [
        'id' => 'product-124',
        'vector' => [0.24, 0.45, 0.97],
        'payload' => ['name' => 'Another Product', 'category' => 'Home']
    ],
    [
        'id' => 'product-125',
        'vector' => [0.25, 0.46, 0.96],
        'payload' => ['name' => 'Third Product', 'category' => 'Office']
    ]
];
Qdrant::batchInsert('products', $points);

// Update vectors
Qdrant::updateVectors('products', [
    [
        'id' => 'product-123',
        'vector' => [0.26, 0.47, 0.95]
    ]
]);

// Delete points
Qdrant::deletePoints('products', ['product-123', 'product-124']);

// Get points by IDs
$points = Qdrant::getPoints('products', ['product-125']);

Search and Recommendations

// Basic vector search
$results = Qdrant::search('products', [0.22, 0.43, 0.95], 10);

// Search with filters
$results = Qdrant::search('products', [0.22, 0.43, 0.95], 10, [
    'must' => [
        ['key' => 'category', 'match' => ['value' => 'Electronics']]
    ]
]);

// Recommendations based on existing points
$recommendations = Qdrant::recommend('products', ['product-125'], [], 5);

Scrolling and Counting

// Scroll through points
$page = Qdrant::scroll('products', 20);
$nextPage = Qdrant::scroll('products', 20, $page['result']['next_page_offset']);

// Count points
$count = Qdrant::count('products');

// Count with filter
$count = Qdrant::count('products', [
    'must' => [
        ['key' => 'category', 'match' => ['value' => 'Electronics']],
    ],
]);

Payload Indexing

// Create an index on a payload field
Qdrant::createFieldIndex('products', 'category', 'keyword');

// Delete a field index
Qdrant::deleteFieldIndex('products', 'category');
