faceting over field not in all documents

[Rebecca Watson <be...@gmail.com>]

hi,

has anyone had experience with faceting over a field where the field
is not present
in all documents within the index?

i'm hoping that -- faceting simply calculates+returns the counts for docs that
have the field present while results may still contain documents that don't
have the facet field (i.e. the field faceted on)?

thanks for any help, i guess if no one has tried this i'll let you know :)

bec :)

Yes, that's exactly what happens. You can use facet.missing to get a count for documents with no value in the facet field too, if you want.
