# Min Aggregation > More info about min aggregation is in the [official elasticsearch docs][1] A single-value metrics aggregation that keeps track and returns the minimum value among numeric values extracted from the aggregated documents. ## Simple example ```JSON { "aggregations" : { "min_price" : { "min" : { "field" : "price" } } } } ``` And now the query via DSL: ```php $minAggregation = new MinAggregation('min_price', 'price'); $search = new Search(); $search->addAggregation($minAggregation); $queryArray = $search->toArray(); ``` [1]: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-min-aggregation.html
