[EP-tech] Re: Search API and name fields (or compound)

I don't think this is possible, I'm afraid.  The way I approach this kind of problem is to iterate over the repository and generate a report.  You could do worse than start with the SCONUL report and modify it to do what you want (save the IDs of items with no author, rather than counting the documents).
