UPGRADE FROM 3.2 to 4.0

Faceted Searching

  • Facets have been removed in Elasticsearch 2.0. Please use aggregations instead.

Before:

     $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();

After:

     $query = new \Elastica\Query();
     $agg = new \Elastica\Aggregation\Terms('tags');
     $agg->setField('companyGroup');
     $query->addAggregation($agg);

     $companies = $finder->findPaginated($query);
     $companies->setMaxPerPage($params['limit']);
     $companies->setCurrentPage($params['page']);

     $aggs = $companies->getAdapter()->getAggregations();
