Query through Elasticsearch Indices with Laravel

Just come across a use case during my daily works, to query through Elasticearch indices, in Laravel.

I'm assuming you have installed Elasticsearch, have indices, index pattern defined and of course, data populated in the index documents.

Then, create a Laravel project and install this Laravel Elasticsearch package.

Then, let's create a file in your laravel project - I've create a directory called tinker/ and created tinker/es.php in it.

Then paste the following codes in the file.

<?php 

$stat = Elasticsearch::indices()->stats(['index'=>'your-index-*']);
$indices = $stat['indices'];
$field = 'username.keyword';
$keyword = 'xyz';
$list = [];
foreach ($indices as $key => $value) {
    echo $key . PHP_EOL;

    $data = [
        'index' => $key,
        'body'  => [
            'query' => [
                'match' => [
                    $field => $keyword,
                ]
            ]
        ]
    ];
    $list[] = Elasticsearch::search($data);
}
dd($list);

Run the above command:

php artisan tinker tinker/es.php

The above code should return something like:

your-index-2021.09.12
array:1 [
  0 => array:4 [
    "took" => 5
    "timed_out" => false
    "_shards" => array:4 [
      "total" => 1
      "successful" => 1
      "skipped" => 0
      "failed" => 0
    ]
    "hits" => array:3 [
      "total" => array:2 [
        "value" => 1
        "relation" => "eq"
      ]
      "max_score" => 0.2876821
      "hits" => array:1 [
        0 => array:5 [
          "_index" => "your-index-2021.09.12"
          "_type" => "_doc"
          "_id" => "xH652nsBOpLioOpWB7gH"
          "_score" => 0.2876821
          "_source" => array:7 [
            "password" => "xyz"
            "username" => "xyz"
            "@timestamp" => "2021-09-12T15:56:03.935Z"
            "port" => 50784
            "tags" => array:1 [
              0 => "your-index"
            ]
            "@version" => "1"
            "host" => "localhost"
          ]
        ]
      ]
    ]
  ]
]
