My recommendation is if you need to query on something, index it as
you need... so in this case index another field with the number of
values in that field. This is easy if you're writing a custom
indexer, but maybe not so trivial if you're indexing other ways - so a
custom update processor could do this for you automatically.

Hi
In a multiValued field, I want to write a query that returns all the
documents that actually have more than 1 value in that field.
(don't care what the value is).
Maybe this should be obvious, but I just can't think of how to
formulate such a query.
Any help?
Thanks,
