Using multiple types or indexes in Elasticsearch php API

Question

I want to query multiple types and indices using Elasticsearch PHP API. but I don't Know how. should I pass an array of types and indices to $params ? :

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

You just add them as a string to $params :

$params['index'] = "index1,index2";// a comma-separated list of index names, without any extra space
$params['type']  = "type1, type2";//array of types
$params['body']  = $q;//query body
//request elasticsearch for matched documents
$results = $client->search($params);
