This method seems to be duplicated in your project.

        foreach ($this->handlers as $handler) {
            if ($handler->accept($criterion)) {

        $filterCreator = \Closure::bind(function($filter){return $this->getParamFilterQuery(array('Filter' => $filter));}, $queryBuilder, $queryBuilder);

The method getParamFilterQuery() does not seem to exist on object<Kaliop\EzFindSearchEngineBundle\Core\Persistence\eZFind\Content\Search\Common\Gateway\CriteriaConverter>.

        return $filterCreator($filter);
    }
