Hi,
Is there a way with faceting or field collapsing to do the SQL equivalent of
SELECT count(distinct(field)) FROM index WHERE length(field) 0 AND
other_criteria
i.e. I'm only interested in the total count not the individual records
and counts.
Cheers,
Dan

advantage: you can look into several fields at one time when adding
another facet.field
disadvantage: you get the counts splitted by
in trunk.

Well, that's true -- you can get the total number of facet values if you
ALSO are willing to get back every facet value in the response.
If you've got a hundred thousand or so unique facet values, and what you
really want is just the _count_ without ALSO getting back a very large
response
