I am getting familiar with exposed filters in Views and so far they work great.
However, I am struggling to make it work with my latest addition. What I would like the exposed filter to do would be with a simple checkbox to filter all those documents (in my case) with data in the field named "field_documentname".
I thought it would be straight forward to make a filter on NOT EMPTY fields, and perhaps the solution is staring right at me. Anyone with a suggestion to a solution is more than welcome.
