Use Elasticsearch from Scratch in Laravel 5 - Laravel Misc.

Elasticsearch is a powerful, open-source search and analytics engine that can be used to search, filter, and aggregate data quickly and easily. In this article, we'll explore how to use Elasticsearch from scratch in Laravel 5.

Installation

Before we can use Elasticsearch in Laravel, we need to install the Elasticsearch PHP client. We can do this using composer:

composer require elasticsearch/elasticsearch

We also need to install the Elasticsearch server if we don't have it installed already. We can download the server from the Elasticsearch website.

Configuration

To use Elasticsearch in Laravel, we need to add the Elasticsearch configuration to the config/database.php file:

'elasticsearch' => [
    'hosts' => [
        env('ELASTICSEARCH_HOST', 'localhost:9200'),
    ],
],

We also need to add the Elasticsearch service provider to the config/app.php file:

'providers' => [
    // Other providers...
    Elasticsearch\ClientServiceProvider::class,
],

Indexing Data

To index data in Elasticsearch, we need to create an instance of the Elasticsearch client:

$client = \Elasticsearch\ClientBuilder::create()
    ->setHosts(config('database.elasticsearch.hosts'))
    ->build();

And then we can use the index() method to add documents to Elasticsearch:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['title' => 'My Title', 'body' => 'My Body'],
];

$response = $client->index($params);

Searching Data

To search data in Elasticsearch, we can use the search() method:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'title' => 'My Title',
            ],
        ],
    ],
];

$response = $client->search($params);

Output

The output of the search will be an array of documents that match the search query.

Explanation

Elasticsearch is a powerful search and analytics engine that can be used to search, filter, and aggregate data quickly and easily. In Laravel, we can use the Elasticsearch PHP client to index and search data in Elasticsearch. We can configure the Elasticsearch client in Laravel and use the index() method to add documents to Elasticsearch and search() method to search the indexed data.

Use

Elasticsearch can be used in Laravel to search, filter, and aggregate data quickly and easily. It's a powerful tool for building search functionality into your Laravel applications.
