 Introducing Elasticsearch DSL library to provide objective query builder for [Elasticsearch bundle](https://github.com/ongr-io/ElasticsearchBundle) and [elasticsearch-php](https://github.com/elastic/elasticsearch-php) client. You can easily build any Elasticsearch query and transform it to an array.

+## Documentation
+
+[The online documentation of the bundle is here](docs/index.md)
+
+## Try it!
+
+### Installation
+
+Install library with [composer](https://getcomposer.org):
+
+```
+composer require ongr/elasticsearch-dsl "~1.0"
+```
+
+### Search
+
+Elasticsearch DSL was extracted from [Elasticsearch Bundle](https://github.com/ongr-io/ElasticsearchBundle) to provide standalone query dsl for [elasticsearch-php](https://github.com/elastic/elasticsearch-php). Examples how to use it together with [Elasticsearch Bundle](https://github.com/ongr-io/ElasticsearchBundle) can be found in the [Elasticsearch Bundle docs](https://github.com/ongr-io/ElasticsearchBundle/blob/master/Resources/doc/search.md).
+
+If you dont want to use Symfony or Elasticsearch bundle, no worries, you can use it in any project together with [elasticsearch-php](https://github.com/elastic/elasticsearch-php). Here's the example:
+
+Install `elasticsearch-php`:
+
+```
+composer require "elasticsearch/elasticsearch": "~2.0"
+```
+
+Create search:
+
+```php
+ <?php
+  require 'vendor/autoload.php';
+  $client = ClientBuilder::create()->build();
+  
+  $matchAll = new ONGR\ElasticsearchDSL\Query\MatchAllQuery();
+  
+  $search = new ONGR\ElasticsearchDSL\Search();
+  $search->addQuery($matchAll)
+  
+  $params = [
+    'index' => 'your_index',
+    'body' => $search->toArray(),
+  ];
+  
+  $results = $client->search($params);
+```
+
+Elasticsearch DSL covers every elasticsearch query, all examples can be found in [the documentation](docs/index.md)
