PHP操做Elasticsearch

 

1、安裝

如下es基於6.4

一、在 composer.json 文件中引入 elasticsearch-php：

{
    "require":{
        "elasticsearch/elasticsearch":"~6.0",
        "monolog/monolog": "~1.0"
    }
}

二、用 composer 安裝客戶端：

curl -s http://getcomposer.org/installer | php
php composer.phar install --no-dev

2、快速開始

一、建立一個test.php文件，內容以下

<?php
require 'vendor/autoload.php';

use Elasticsearch\ClientBuilder;


$hosts = [
    '192.168.16.241:9200',         // IP + Port
    '192.168.16.241',              // Just IP
    'localhost:9200', // Domain + Port
    'localhost',     // Just Domain
    'http://localhost',        // SSL to localhost
    'https://192.168.16.241:9200'  // SSL to IP + Port
];
$client = ClientBuilder::create()->setHosts($hosts)->build();            // Instantiate a new ClientBuilder  // Set the hosts


$params = [
    'index'  => 'test_data',
    'type'   => 'users',
    'id'     => 100027,
    'client' => [ 'ignore' => 404 ]
];
var_dump( $client->get($params));

二、瀏覽器訪問test.php，結果以下（前提是你的es已經有數據）

3、基本操做

一、建立索引

$params = [
    'index' => 'test_index'
];

// Create the index
print_r($client->indices()->create($params));

二、建立索引（指定模板）

$params = [
    'index' => 'test_index',
    'body' => [
        'settings' => [
            'number_of_shards' => 5,
            'number_of_replicas' => 2
        ],
        'mappings' => [
            'test_type' => [
                '_source' => [
                    'enabled' => true
                ],
                'properties' => [
                    'name' => [
                        'type' => 'text',
                        'analyzer' => 'ik_max_word'
                    ],
                    'age' => [
                        'type' => 'integer'
                    ]
                ]
            ]
        ]
    ]
];
// Create the index with mappings and settings now
print_r($client->indices()->create($params));

三、刪除索引、

$params = ['index' => 'test_index'];
print_r($client->indices()->delete($params));

四、更改索引的配置參數:

$params = [
    'index' => 'test_index',
    'body' => [
        'settings' => [
            'number_of_replicas' => 0,
            'refresh_interval' => -1
        ]
    ]
];

print_r($client->indices()->putSettings($params));

五、獲取一個或多個索引的當前配置參數

$params = [
    'index' => [ 'test_index', 'test_data' ]
];
print_r($client->indices()->getSettings($params));

六、更改或增長一個索引的映射

$params = [
    'index' => 'test_index',
    'type' => 'test_type',
    'body' => [
        'test_type' => [
            '_source' => [
                'enabled' => true
            ],
            'properties' => [
                'name' => [
                    'type' => 'text',
                    'analyzer' => 'ik_max_word'
                ],
                'age' => [
                    'type' => 'integer'
                ],
                'createtime' => [
                    'type' => 'date'  //加了一個時間
                ]

            ]
        ]
    ]
];

// Update the index mapping
print_r($client->indices()->putMapping($params));

七、返回索引和類型的映射細節

$response = $client->indices()->getMapping();

// Get mappings for all types in 'my_index'
$params = ['index' => 'my_index'];
$response = $client->indices()->getMapping($params);

// Get mappings for all types of 'my_type', regardless of index
$params = ['type' => 'my_type' ];
$response = $client->indices()->getMapping($params);

// Get mapping 'my_type' in 'my_index'
$params = [
    'index' => 'my_index'
    'type' => 'my_type'
];
$response = $client->indices()->getMapping($params);

// Get mappings for two indexes
$params = [
    'index' => [ 'my_index', 'my_index2' ]
];
$response = $client->indices()->getMapping($params);

八、索引一個文檔（提供id，則會更新對應id的記錄。若沒有提供，則會生成一條文檔）

$params = [
    'index' => 'test_data',
    'type' => 'users',
    'id' => '100027',
    'body' => [ 'nickname' => 'update222']
];

// Document will be indexed to my_index/my_type/my_id
print_r($client->index($params));

九、獲取文檔

$params = [
    'index' => 'test_data',
    'type' => 'users',
    'id' => '100027'
];

// Get doc at /my_index/my_type/my_id
print_r($client->get($params));

十、更新文檔 （doc指定要更新的字段內容）

$params = [
    'index' => 'test_data',
    'type' => 'users',
    'id' => '100027',
    'body' => [
        'doc' => [
            'nickname' => 'abc',
            'mobile' => '13800138000'
        ]
    ]
];
// Update doc at /my_index/my_type/my_id
print_r($client->update($params));

十一、執行一個腳本進行更新，對某個字段的數據進行拼接或自增

$params = [
    "index" => "test_data",
    "type" => "users",
    "id" => "100027",
    "body" => [
        "script" => "ctx._source.nickname += 'hahh'"
    ]
];

print_r($client->update($params));

十二、刪除文檔

$params = [
    'index' => 'test_data',
    'type' => 'users',
    'id' => '100027'
];

// Delete doc at /my_index/my_type/my_id
print_r($client->delete($params));

1三、搜索內容

$json = '{
    "query" : {
        "match" : {
            "id" : "100073"
        }
    }
}';

$params = [
    'index' => 'test_data',
    'type' => 'users',
    'body' => $json
];
print_r($client->search($params));


$params = [
    'index' => 'test_data',
    'type' => 'users',
    'body' => [
        'query' => [
            'bool' => [
                'should' => [
                    [ 'match' => [ 'nickname' => [
                        'query' => 'user440032',
                        'boost' => 3, // 權重大
                    ]]]
                ],
            ],
        ],
        'sort' => ['id'=>['order'=>'desc']]     //排序   分頁
        , 'from' => 0, 'size' => 10
    ]
];

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