Hi Ferran,
Since you're running Invenio-1.1 you could use the authorcount index: a
search for authorcount:1+ would retrieve all records that have at least
one author.

Hi,
we need to create an oai set, based on certain collections, but where
the author field must exist. We have tried several variations of
regular expression search but with no luck. We'd be happy if we can
text for the existence of a 100 field, if it is easier than author.
Thanks,
Ferran
