如何使用Elastica进行查询

Won*_*der 4 php elasticsearch elastica

这是我第一次使用Elastica并查询ElasticSearch的数据

对我来说,作为首发,我有一个问题,如何使用Elastica查询下面的代码?:

curl 'http://localhost:9200/myindex/_search?pretty=true' -d '{     
  "query" : {
    "term": {
      "click": "true"
    }   },   "facets" : {
    "matches" : {
      "terms" : {
          "field" : "pubid",
          "all_terms" : true,
          "size": 200 
      }
    }   
  } 
}'

希望有人能借给我一臂之力.

这应该做:

// Create a "global" query
$query = new Elastica_Query;

// Create the term query
$term = new Elastica_Query_Term;
$term->setTerm('click', 'true');

// Add term query to "global" query
$query->setQuery($term);

// Create the facet
$facet = new Elastica_Facet_Terms('matches');
$facet->setField('pubid')
      ->setAllTerms(true)
      ->setSize(200);

// Add facet to "global" query
$query->addFacet($facet);

// Output query
echo json_encode($query->toArray());

要运行查询,您需要连接到ES服务器

// Connect to your ES servers
$client = new Elastica_Client(array(
    'servers' => array(
        array('host' => 'localhost', 'port' => 9200),
        array('host' => 'localhost', 'port' => 9201),
        array('host' => 'localhost', 'port' => 9202),
        array('host' => 'localhost', 'port' => 9203),
        array('host' => 'localhost', 'port' => 9204),
    ),
));

并指定要对其运行查询的索引和类型

// Get index
$index = $client->getIndex('myindex');
$type = $index->getType('typename');

现在您可以运行查询

$type->search($query);

编辑:如果您使用的是命名空间环境和当前版本的Elastica,请更改创建新对象的所有行

$query = new \Elastica\Query;
$facet = new \Elastica\Facet\Terms
