Hi ES Java High Level REST Client team,  
I am using ES Java High Level REST Client 6.8.0 version.  
I want to know whether there is some function, like the JSON parser, to be able to covert String type query to `QueryBuilder` object. The String type query is the result of running the `toString() ` method of `AbstractQueryBuilder` by some XXQueryBuilder object

E.g.  
In our case, there is a microservice providing ACL ES query string which will be used by end user as a part of an ES query, to be as an ACL condition.

E.g.:

```auto
   QueryBuilders aclBoolQuery = QueryBuilders.boolQuery()
                    .must(QueryBuilders.termQuery("A", "RF"))
                    .must(QueryBuilders.termQuery("B", "EF"))
                    .must(QueryBuilders.termQuery("C", "RF"));
return aclBoolQuery.toString(false);

```

In another microservice to consume the string type query

```auto
  QueryBuilders businessBoolQuery=...

  String aclBoolQuery=rpcClient.callAclService(aclRequest);
  QueryBuilder acl= QueryBuilders.parse(aclBoolQuery); // expected function

  businessBoolQuery.filter(acl);
  ...

```

It is easily to use by Python client. But for ES Java High Level REST Client I can not find any API that can parse the query string.

I guess it should be somewhere or there should be a good reason without providing this feature.

Thank you!  
Bruce

Hi @Bruce_Zu  
I think you are looking for [wrapper query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wrapper-query.html).

```auto
new SearchSourceBuilder().query(QueryBuilders.wrapperQuery("json_query"));

```

@RabBit_BR  
Thank you so much for shedding light here!  
That is just what I want. Awesome feature!
