Examples
Example #1 SolrQuery::collapse() example
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
'path' => SOLR_SERVER_PATH
);
$client = new SolrClient($options);
$query = new SolrQuery('*:*');
$collapseFunction = new SolrCollapseFunction('manu_id_s');
$collapseFunction
->setSize(2)
->setNullPolicy(SolrCollapseFunction::NULLPOLICY_IGNORE);
$query
->collapse($collapseFunction)
->setRows(4);
$queryResponse = $client->query($query);
$response = $queryResponse->getResponse();
print_r($response);
?>
