From manual page: http://www.php.net/solrquery.getgrouplimit
---


Using the setGroupLimit() function of the SolrQuery object does not actually add the group.limit parameter to the query string being sent to the solr server.

As a work around, I have to manually specify it using setParam()


i.e.  setParam('group.limit', 200);

Test script:
---------------
const SOLR_QUERY_ALL = '*:*';

// ...

$this->solrQuery = new SolrQuery(self::SOLR_QUERY_ALL);
$this->solrClient = new SolrClient('catalog');

// ...
$this->solrQuery->setGroup(true);
$this->solrQuery->setGroupNGroups(true); 
$this->solrQuery->setGroupMain(false);
$this->solrQuery->getGroupLimit(200); // DOES NOT ACTUALLY DO ANYTHING!

// ...

$query_response = $this->solrClient->query($this->solrQuery);  
$this->response = get_object_vars($query_response->getResponse()); 

print_r($this->response);

Expected result:
----------------
Array
(
    [responseHeader] => SolrObject Object
        (
            [status] => 0
            [QTime] => 75
            [params] => (...
                        )

                    [indent] => on
                    [group.limit] => 200
                    [start] => 0
                    [facet.missing] => true
                    [fq] => Array
                        (
                            ...
                        )

                    [rows] => 25
                    [group.ngroups] => true
                    [version] => 2.2
                    [q] => *:*
                    [facet.limit] => -1
                    [group.main] => false
                    [facet.threads] => 6
                    [facet.mincount] => 1
                    [wt] => xml
                    [facet] => true
                    [group.field] => product_id
                    [group] => true
                )

        )
