php - Multy如何获取Elasticsearch php的样本？

Question

在 php 中利用 Elasticsearch 客户端。我如何在 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？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!)

您只需要使用 ids过滤器，像这样:

$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);
