# Terms Aggregation > More info about terms aggregation is in the [official elasticsearch docs][1] A multi-bucket value source based aggregation where buckets are dynamically built - one per unique value. ## Simple example ```JSON { "aggregations" : { "agg_genders" : { "terms" : { "field" : "gender" } } } } ``` And now the query via DSL: ```php $termsAggregation = new TermsAggregation('genders', 'gender'); $search = new Search(); $search->addAggregation($termsAggregation); $queryArray = $search->toArray(); ``` [1]: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html
