+# Range Filter
+
+> More info about range filter is in the [official elasticsearch docs][1]
+
+Filters documents with fields that have terms within a certain range.
+
+## Simple example
+
+```JSON
+{
+ "filter" : {
+ "range" : {
+ "age" : {
+ "gte": 10,
+ "lte": 20
+ }
+ }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$rangeFilter = new RangeFilter('age', ['gte' => 10, 'lte' => 20]);
+
+$search = new Search();
+$search->addFilter($rangeFilter);
+
+$queryArray = $search->toArray();
+```
