+$query = new \Elastica\Query();
+$facet = new \Elastica\Facet\Terms('tags');
+$facet->setField('companyGroup');
+$query->addFacet($facet);
+
+$companies = $finder->findPaginated($query);
+$companies->setMaxPerPage($params['limit']);
+$companies->setCurrentPage($params['page']);
+
+$facets = $companies->getAdapter()->getFacets());
