Apache Solr for TYPO3 CMS

This is tx_solr 2.1.0 on php 5.3.13:

The following fails:

$query = t3lib_div::makeInstance('tx_solr_Query', '*:*');
$parameters['fl'] = 'uid,type';
$parameters['fq'] = 'appKey:EXT\:myextkey AND type:' . $table;
$response = $solr->search($query, 0, 10000, $parameters);

what makes the url work is to add a &q=*:* - the q parameter goes missing on the way.

Fix by typecast:

class tx_solr_SolrService extends Apache_Solr_Service {
    ...
    public function search($query, $offset = 0, $limit = 10, $params = array()) {
        $response = parent::search((string)$query, $offset, $limit, $params);
        ...
    }
    ...
}

Apparently the builtin

http_build_query

called in

Apache_Solr_Service::_generateQueryString

called in

Apache_Solr_Service::search

drops

$params['q'] => $query<tx_solr_Query>

instead of invoking

__toString()

.
