Multy 如何获取 Elasticsearch php 的样本？

Question

在 php 中利用 Elasticsearch 客户端。怎么在ES中找到很多文档，对于id，在SQL中等于"WHERE id IN (1,2,3,4,9)"？对于单声道，我这样做

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

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

如何获取一些记录？我试过了，还是不行

$ params = [[
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id'
  ]
  [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id2'
  ]];

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

等等

$ params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => array ('my_id', 'my_id2')
  ];

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

API是PHP只有https：https://www.elastic.co/guide/en/elasticsearch/client/php-api/2.0/_getting_documents.html

就是这样，只有CURL请求https:https://www.elastic.co/guide/en/elasticsearch/reference/1.4/docs-multi-get.html

谁用过ES，请帮忙！）

Answer 1

您只需使用 ids 过滤器，如下所示：

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'filtered' => [
                'filter' => [
                    'ids' => [ 
                        'values' => ['my_id', 'my_id2'] 
                    ]
                ]
            ]
        ]
    ]
];


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

更新

如果你绝对想使用mget，那么你应该这样做：

$ params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => ['ids' => ['my_id', 'my_id2']]
  ];

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

Answer 2

只需在插入过程中添加下面一行

"refresh"=> true

Answer 3

阅读源代码\vendor\elasticsearch\elasticsearch\src\Elasticsearch\Client.php和mget函数。你应该这样做：

$params = [
        'index' => 'index',
        'type' => 'type',
        'body' => array('ids' => array('id1', 'id2'))
      ];
    
    $response = $ client-> mget ($ params);
    foreach ($response ['docs'] as $doc)
    {
        $source = $doc['_source'];
    }
