Non-analyzed Field Must Be Null

Elastic Stack Elasticsearch
1

How can I query to return only documents with a certain non-analyzed field equal null? I tried this, but it didn't work:

{"wildcard":{"MyField":{"value":null}}}

2

This seems to work. Is there a better (more correct) way?

{"field":{"MyField":{"query":"-*"}}}
