Hello Gurus, I am relatively new to the group. I am posting the below query via JAVA API and seeing error as follows. Not sure what i am missing.

Request Body : {"query":{"match\_all":{"boost":1.0}}}

Error response:

{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"Unknown key for a START\_OBJECT in [queryBuilder].","line":1,"col":17}],"type":"parsing\_exception","reason":"Unknown key for a START\_OBJECT in [queryBuilder].","line":1,"col":17},"status":400}

At the same time if use the same request body in postman, the same works fine.

`
MatchAllQueryBuilder queryBuilder = QueryBuilders.matchAllQuery();
```
  SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
  searchSourceBuilder.query(queryBuilder);
  
  SearchModule searchModule = new SearchModule(Settings.EMPTY, false, Collections.emptyList());
  try (XContentParser parser = XContentFactory.xContent(XContentType.JSON)
        .createParser(new NamedXContentRegistry(searchModule.getNamedXContents()), searchSourceBuilder.toString())) {
     searchSourceBuilder.parseXContent(parser);
  }

```
`

I am using SearchSourceBuilder to build a match\_all query and passing the same as part of the request. Please let me know in case of more details needed.

Why are you calling `SearchModule`?

This should be fine:

```auto
SearchRequest searchRequest = new SearchRequest(); 
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); 
searchSourceBuilder.query(QueryBuilders.matchAllQuery()); 
SearchResponse searchResponse = client.search(searchRequest);

```

Thanks for the reply @dadoonet, I am not using client , we have our own implementation of service call. Tied the above and i see below error.

{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"Unknown key for a VALUE\_NULL in [remoteAddress].","line":1,"col":18}],"type":"parsing\_exception","reason":"Unknown key for a VALUE\_NULL in [remoteAddress].","line":1,"col":18},"status":400}

I believe SearchRequest is suitable for the Client based request. I am wondering on what to use when custom rest implementation is used (Like cxf, jersey..etc)

I just need to create a body with json data and invoke the service. Hope this helps.

Would that work?

```
    SearchSourceBuilder sb = new SearchSourceBuilder();
    sb.query(QueryBuilders.matchAllQuery());
    String json = sb.toXContent(XContentFactory.jsonBuilder(), ToXContent.EMPTY_PARAMS).string();
```
