安装拓展

#### composer安装
composer require elasticsearch/elasticsearch

基础使用

1. 实例化一个客户端 ```php require ‘vendor/autoload.php’;

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();

2. 索引一个文档
```php
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => 'abc']
];

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

1. 获取一个文档

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

$response = $client->get($params);
print_r($response);

1. 搜索一个文档 ```php $params = [ ‘index’ => ‘my_index’, ‘type’ => ‘my_type’, ‘body’ => [

    'query' => [
        'match' => [
            'testField' => 'abc'
        ]
    ]
   

   ] ];

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

5. 删除一个文档
```php
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id'
];

$response = $client->delete($params);
print_r($response);

1. 删除索引

   $deleteParams = [
    'index' => 'my_index'
   ];
   $response = $client->indices()->delete($deleteParams);
   print_r($response);
   

2. 创建索引 ```php $params = [ ‘index’ => ‘my_index’, ‘body’ => [

    'settings' => [
        'number_of_shards' => 2,
        'number_of_replicas' => 0
    ]
   

   ] ];

$response = $client->indices()->create($params); print_r($response); ```
