Solr Search For Documents That Has Empty Content For a Given Particular Field

[Furkan KAMACI]

Hi;

How can I find the documents that has empty content for a given field. I
don't mean something like:

-field:[* TO *]

because it returns the documents that has not given particular field. I
have documents something like:

"field1":"some text",
"field2":"some text",
"field" : "" // this is the field that I want to learn which document has
it.

Thanks;
