Using multiple types or indexes in Elasticsearch php API -

i want query multiple types , indices using elasticsearch php api. don't know how. should pass array of types , indices $params ? :

$params['index'] = $index;//array of indices $params['type']  = $types;//array of types $params['body']  = $q;//query body //request elasticsearch matched documents $results = $client->search($params); 

you add them string $params :

$params['index'] = "index1,index2";//array of indices $params['type']  = "type1,type2";//array of types $params['body']  = $q;//query body //request elasticsearch matched documents $results = $client->search($params);
