Hi Claes, I think this is not possible with Zebra, at least I haven't seen a query for doing that so far. Katrin On 18.09.2018 16:56, Claes Eriksson wrote:

I would like to search and find records without data in a specific field. An example:

Go to advanced search in the OPAC and opt for More options.

Search with some word in the "Title" field and in the field "Conference name" I would like to find those records that has no data in that field.

I can solve this specific question with a SQL report but I wonder if it is possible to do the same with a simple search?
