README

This package was inspired by the Plastic package, which provided a similar integration for Elasticsearch. Oponka builds upon the concepts established by Plastic, adapting them for the OpenSearch ecosystem. However, unlike Plastic, Oponka focuses solely on OpenSearch and does not include functionality for mapping indices to Eloquent models.

Oponka provides a seamless integration with OpenSearch for Laravel applications (version 10 and above). It simplifies the process of interacting with OpenSearch, allowing you to easily perform searches, index documents, and manage your OpenSearch data.

Features

Native OpenSearch Library: Utilizes the official OpenSearch PHP client for direct and efficient communication with your OpenSearch cluster.
OpenSearch DSL: Leverages the opensearch-dsl library to provide a more intuitive and expressive syntax for building complex search queries.
Easy Configuration: Simple configuration options allow you to quickly connect to your OpenSearch cluster and customize the package's behavior.
Laravel Integration: Integrates seamlessly with Laravel's service container and provides convenient helpers for accessing OpenSearch functionality within your application.

Installation

Install the package using Composer:

php composer require nuwber/oponka

Configuration

The OponkaServiceProvider will be used automatically as it is configured in the composer.json file.

If you need it in your project, you can use the following commands:

php artisan vendor:publish --provider="Nuwber\Oponka\OponkaServiceProvider"

Configure the Oponka connection:

Open the config/oponka.php file and change the connection settings as needed. Or do it with .env file.

Usage

The primary way to interact with Oponka is through the Oponka facade.

Getting the Client

You can access the underlying OpenSearch PHP client instance directly if needed:

use Nuwber\Oponka\Facades\Oponka;

$client = Oponka::client(); 
// Now you can use the $client directly with the OpenSearch PHP client methods

Indexing Documents

To index a document, you can use the index method:

use Nuwber\Oponka\Facades\Oponka;

$params = [
    'index' => 'my_index',
    'id'    => 'my_id',
    'body'  => ['testField' => 'abc']
];

$response = Oponka::index($params);

// $response contains the OpenSearch response array

Searching Documents

Oponka integrates with opensearch-dsl/opensearch-dsl. You can build your queries using its syntax.

use Nuwber\Oponka\Facades\Oponka;
use OpenSearchDSL\Search;
use OpenSearchDSL\Query\Compound\BoolQuery;
use OpenSearchDSL\Query\TermLevel\TermQuery;
use OpenSearchDSL\Query\FullText\MatchQuery;

// Get the DSL Search object
$search = Oponka::search(); // Or potentially a method to get a new Search object

// Build a query
$query = new BoolQuery();
$query->add(new MatchQuery('title', 'laravel'));
$query->add(new TermQuery('status', 'published'), BoolQuery::FILTER);

$search->addQuery($query);
$search->setSource(['title', 'status', 'publish_date']);
$search->setSize(10);
$search->setFrom(0); // for pagination

// Prepare the parameters for OpenSearch
$params = [
    'index' => 'my_index',
    'body' => $search->toArray(),
];

// Execute the search
$results = Oponka::search($params); 

// Process results (assuming a Result object or similar is returned)
// foreach ($results->getHits() as $hit) {
//     // Access hit data: $hit['_source'], $hit['_score'], etc.
// }
// $total = $results->getTotal();

Note: The exact methods for accessing the DSL builder and processing results might differ slightly. Please refer to the source code or tests for precise implementation.

Updating Documents

Use the update method:

use Nuwber\Oponka\Facades\Oponka;

$params = [
    'index' => 'my_index',
    'id'    => 'my_id',
    'body'  => [
        'doc' => [
            'new_field' => 'xyz'
        ]
    ]
];

$response = Oponka::update($params);

Deleting Documents

Use the delete method:

use Nuwber\Oponka\Facades\Oponka;

$params = [
    'index' => 'my_index',
    'id'    => 'my_id'
];

$response = Oponka::delete($params);

Direct Client Access

For operations not directly exposed or for more complex scenarios, you can always fall back to the native OpenSearch client:

use Nuwber\Oponka\Facades\Oponka;

$client = Oponka::client();

$response = $client->cat()->indices(['index' => 'my_index', 'v' => true]);
