Search for notes where certain field is not empty

While running my latest tests i realized i am not able to search for non-empty fields. For example: show me all notes containing a remark, no matter what that remarks looks like. Actually this feature could be implemented by automatically limiting the search scope to non-empty values, when i select the appropriate filter. This would affect "Any Text field", "Text+Title", "Text only", "Title only", "Remarks" and "Link". In other words, if i select "Remarks", the result list would show me all notes where remarks has some value. A special filter is applied only, when i start typing some value. (Thomas Lohrum)
