### Examples

Example #1 SolrQuery::addFacetField() example

    <?php$options = array(        'hostname' => SOLR_SERVER_HOSTNAME,        'login'    => SOLR_SERVER_USERNAME,        'password' => SOLR_SERVER_PASSWORD,        'port'     => SOLR_SERVER_PORT,);$client = new SolrClient($options);$query = new SolrQuery('*:*');$query->setFacet(true);$query->addFacetQuery('price:[* TO 500]')->addFacetQuery('price:[500 TO *]');$query_response = $client->query($query);$response = $query_response->getResponse();print_r($response->facet_counts->facet_queries);?>

The above example will output something similar to:

    SolrObject Object
    (
        [price:[* TO 500]] => 14
        [price:[500 TO *]] => 2
    )
