Hi,  
First of all, thanks for a great library. I'm using the Java API, and  
I have run into a small problem.  
The class org.elasticsearch.index.query.json.BoolJsonFilterBuilder is  
declared in the following way:

```
public class BoolJsonFilterBuilder extends BaseJsonQueryBuilder {
    ...
}

```

This looks like a bug. Should it not extend BaseJsonFilterBuilder  
instead?  
This prevents me from using BoolJsonFilterBuilder as  
JsonFilterBuilder.

Regards,  
OGG
