+# Query Filter
+
+> More info about query filter is in the [official elasticsearch docs][1]
+
+Wraps any query to be used as a filter.
+
+## Simple example
+
+```JSON
+{
+ "filter" : {
+ "query" : {
+ "query_string" : {
+ "query" : "this AND that OR thus"
+ }
+ }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$queryStringQuery = new QueryStringQuery('this AND that OR thus');
+$queryFilter = new QueryFilter($queryStringQuery);
+
+$search = new Search();
+$search->addFilter($queryFilter);
+
+$queryArray = $search->toArray();
+```
