这应该这样做:
// 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,您需要连接到您的 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,请将创建新对象的所有行相应更改为
$query = new \Elastica\Query;
$facet = new \Elastica\Facet\Terms
等等
