Searchcraft API PHP Client Library

The Searchcraft API PHP Client is a fully PSR-compatible PHP client that acts as a language specific wrapper around the Searchcraft API.

Prerequisites

To use the client library you will need to have the following installed:

• PHP 8.0 or higher
• Composer

Installation

composer require searchcraft/searchcraft-php

You will also need to install a PSR-18 compatible HTTP client, such as Guzzle.

composer require guzzlehttp/guzzle http-interop/http-factory-guzzle:^1.0

Basic Usage

Initialize the client

The client can be initialized with different types of API keys, depending on your access requirements:

use Searchcraft\Searchcraft;

// Using an admin key (full access)
$searchcraft_full = new Searchcraft('your-admin-key', Searchcraft::KEY_TYPE_ADMIN);

// Using a read-only key (search and read operations only)
$searchcraft_reader = new Searchcraft('your-read-key', Searchcraft::KEY_TYPE_READ);

// Using an ingest key (document operations only)
$searchcraft_ingestion = new Searchcraft('your-ingest-key', Searchcraft::KEY_TYPE_INGEST);

By default, the client connects to http://localhost:8000. To use a different endpoint such as a Searchcraft Cloud cluster:

// Replace with your cluster endpoint
$searchcraft = new Searchcraft(
    'your-api-key',
    Searchcraft::KEY_TYPE_ADMIN,
    'https://yourcluster.io'
);

Using PSR-18 HTTP Client

The client uses PSR-18 HTTP Client discovery to find an available HTTP client. You can also provide your own:

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\HttpFactory;

$httpClient = new Client();
$requestFactory = new HttpFactory();
$streamFactory = new HttpFactory();

$searchcraft = new Searchcraft(
    'your-api-key',
    Searchcraft::KEY_TYPE_ADMIN,
    'https://api.searchcraft.io/v1',
    $httpClient,
    $requestFactory,
    $streamFactory
);

Searchcraft PHP Client does not include a specific HTTP client in its require dependencies but Guzzle is recommended. You will need to install one in order to use the Searchcraft client.

Search Operations

Search operations require an admin key or read key.

Basic Search

// Simple search query
$results = $searchcraft->search()->query('my_index', 'search term');

// Search with additional parameters
$results = $searchcraft->search()->query('my_index', 'search term', [
    'limit' => 20,
    'offset' => 0,
    'sort' => 'price:asc',
    'mode' => 'fuzzy'
]);

// Fuzzy search (default)
$results = $searchcraft->search()->query('my_index', 'search term');

// Explicit fuzzy search
$results = $searchcraft->search()->query('my_index', 'search term', ['mode' => 'fuzzy']);

// Exact search
$results = $searchcraft->search()->query('my_index', 'search term', ['mode' => 'exact']);

Federation Search

// Search across all indexes in a federation using federatedQuery
$searchResults = $searchcraft->search()->federatedQuery('my_federation', 'breaking news', [
    'limit' => 20,
    'offset' => 0,
    'mode' => 'fuzzy'
]);

// Federation search with additional options
$searchResults = $searchcraft->search()->federatedQuery('my_federation', 'search term', [
    'limit' => 50,
    'offset' => 10,
    'order_by' => 'publishedAt',
    'sort' => 'desc',
    'occur' => 'should',
    'mode' => 'exact'
]);

Index Operations

Index administration operations require an admin key.

List Indexes

$indexes = $searchcraft->index()->listIndexes();

Get Index Details

$indexDetails = $searchcraft->index()->getIndex('products');

Create Index

$newIndex = $searchcraft->index()->createIndex('blog', [
    'index' => [
        'name' => 'blog',
        'language' => 'en',
        'search_fields' => ['title', 'content', 'tags'],
        'fields' => [
            'id' => [
                'type' => 'text',
                'required' => true,
                'stored' => true,
                'indexed' => false
            ],
            'title' => [
                'type' => 'text',
                'stored' => true
            ],
            'content' => [
                'type' => 'text',
                'stored' => true
            ],
            'tags' => [
                'type' => 'text',
                'stored' => true,
                'multi' => true
            ],
            'category' => [
                'type' => 'facet',
                'stored' => true
            ],
            'publishedAt' => [
                'type' => 'datetime',
                'fast' => true,
                'stored' => true,
                'indexed' => true
            ]
        ],
        'weight_multipliers' => [
            'title' => 2.0,
            'tags' => 1.0,
            'content' => 0.6
        ]
    ]
]);

Update Index

Note if you are not adding, removing or changing properties of schema fields will likely want to use the PATCH operation instead. An update request will remove existing documents but for patchable updates your index is not emptied. See the docs for details on which properties are patchable.

$updatedIndex = $searchcraft->index()->updateIndex('blog', [
    'index' => [
        'name' => 'blog',
        'language' => 'en',
        'search_fields' => ['title', 'content', 'tags', 'summary'],
        'fields' => [
            'id' => [
                'type' => 'text',
                'required' => true,
                'stored' => true,
                'indexed' => false
            ],
            'title' => [
                'type' => 'text',
                'stored' => true
            ],
            'content' => [
                'type' => 'text',
                'stored' => true
            ],
            'summary' => [
                'type' => 'text',
                'stored' => true
            ],
            'tags' => [
                'type' => 'text',
                'stored' => true,
                'multi' => true
            ],
            'category' => [
                'type' => 'facet',
                'stored' => true
            ],
            'publishedAt' => [
                'type' => 'datetime',
                'fast' => true,
                'stored' => true,
                'indexed' => true
            ]
        ],
        'weight_multipliers' => [
            'title' => 2.0,
            'content' => 1.0,
            'summary' => 1.5
        ]
    ]
]);

Patch Index

$patchedIndex = $searchcraft->index()->patchIndex('blog', [
    'search_fields' => ['title', 'content', 'tags', 'summary'],
    'weight_multipliers' => [
        'title' => 3.0,
        'content' => 1.0,
        'summary' => 1.5,
        'tags' => 0.8
    ],
    'language' => 'en',
    'time_decay_field' => 'publishedAt',
    'auto_commit_delay' => 2,
    'exclude_stop_words' => true
]);

Delete Index

$result = $searchcraft->index()->deleteIndex('my-index');

Document Operations

Document operations require an admin key or ingest key.

Add Documents

$result = $searchcraft->index()->addDocuments('products', [
    [
        'id' => '1',
        'name' => 'Smartphone X',
        'price' => 699.99,
        'category' => 'Electronics',
        'brand' => 'BrandName'
    ],
    [
        'id' => '2',
        'name' => 'Laptop Pro',
        'price' => 1299.99,
        'category' => 'Electronics',
        'brand' => 'BrandName'
    ]
]);

Update Documents

$result = $searchcraft->index()->updateDocuments('products', [
    [
        'id' => '1',
        'price' => 649.99,
        'in_stock' => true
    ]
]);

Get Document

$document = $searchcraft->index()->getDocument('products', '1');

Delete Documents

$result = $searchcraft->index()->deleteDocuments('products', ['1', '2']);

Federation Operations

Federation operations allow you to manage federations that combine multiple indexes for cross-index search. Federation administration operations require an admin key, while federation search requires a read key.

List Federations

// List all federations
$federations = $searchcraft->federation()->listFederations();

Get Federation Details

// Get details of a specific federation
$federation = $searchcraft->federation()->getFederation('galaxy_news_federation');

Get Federations by Organization

// Get all federations for a specific organization
$organizationFederations = $searchcraft->federation()->getFederationsByOrganization('4');

Create Federation

// Create a new federation with weighted index configurations
$newFederation = $searchcraft->federation()->createFederation([
    'name' => '4_galaxy_news_test',
    'friendly_name' => 'Galaxy News Test Federation',
    'created_by' => '1',
    'last_modified_by' => '1',
    'organization_id' => '4',
    'index_configurations' => [
        [
            'name' => 'news_articles',
            'weight_multiplier' => 1.0
        ],
        [
            'name' => 'blog_posts',
            'weight_multiplier' => 0.8
        ],
        [
            'name' => 'press_releases',
            'weight_multiplier' => 1.5
        ]
    ]
]);

Update Federation

// Update an existing federation
$updatedFederation = $searchcraft->federation()->updateFederation('galaxy_news_federation', [
    'friendly_name' => 'Updated Galaxy News Federation',
    'last_modified_by' => '1',
    'organization_id' => '4',
    'index_configurations' => [
        [
            'name' => 'news_articles',
            'weight_multiplier' => 1.2
        ],
        [
            'name' => 'blog_posts',
            'weight_multiplier' => 0.9
        ],
        [
            'name' => 'press_releases',
            'weight_multiplier' => 1.8
        ],
        [
            'name' => 'social_media',
            'weight_multiplier' => 0.6
        ]
    ]
]);

Delete Federation

// Delete a federation
$result = $searchcraft->federation()->deleteFederation('old_federation');

Error Handling

All operations should be wrapped in a try/catch block to handle errors:

use Searchcraft\Exception\SearchcraftException;

try {
    $results = $searchcraft->search()->query('products', 'smartphone');
} catch (SearchcraftException $e) {
    echo 'Error: ' . $e->getMessage();
}
