Hmmm, Once the data is included in the catch-all, it's indistinguishable from all the rest of the data, so I don't see how you could do this. A clause like: -excludeField:[* TO *] would exclude all documents that had any data in the field so that's probably not what you want.....
Could you approach it the other way? Do NOT put the special field in the catch-all field in the first place, but massage the input to add a clause there? I.e. your "usual" case would have catchall:<all your terms> exclude_field:<all your terms>, but your special one would just be catchall:<all your terms>. You could set up request handlers to do this under the covers, so your queries would really be ...solr/usual?q=<all your terms> ...solr/special?q=<all your terms> and two different request handlers (edismax-style I'm thinking) would differ only by the "qf" field containing or not containing your special field..... the other way, of course, would be to have a second catch-all field that didn't have your special field, then use one or the other depending, but as you say that would increase the size of your index...
