Hi, I'm working with elasticsearch-dsl package (version 2.5)

This is my query being formed with the help of elasticsearch-dsl package.

Python code for building query:

```auto
if self._filters:
    base = base.filter('bool', must=self._filters)

```

where `self._filters = []` is class constructor and it returns me this query:

```auto
{
    'must': 
        [
           Term(id=28300)
        ]
}

```

I'm facing some issues with it. There is some class in elasticsearch-dsl package like this:

```auto
Query.get_dsl_class(name_or_query)(**params)

```

and `get_dsl_class` method looks like this:

```auto
def get_dsl_class(cls, name):
    try:
        return cls._classes[name] <-- throwing error from here
    except KeyError:
        raise UnknownDslObject('DSL class `%s` does not exist in %s.' % (name, cls._type_name))

```

I'm getting this error: "TypeError: unhashable type: "Term"". I'm not sure how to fix it and wanted to have some context over it. It would be great if someone can help me with this issue, will really appreciate it. 🙂
