How to find null_value in query_string like we can in missing filter

I'm using elasticsearch v0.90.5

With a missing filter, we can track missing fields:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-missing-filter.html
and make sure that a null_value also counts as missing.

How can we do the same in a query_string?
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_field_names
Based on my test so far, the non-existent field counts as missing but the
null_value field counts as present.

How should I write my query?

Can anyone help with this comparison between missing fields in filter vs.
query?
