searching top matches of each facet

[Paul <pa...@nines.org>]

Let's say that I have a facet named 'subject' that contains one of:
physics, chemistry, psychology, mathematics, etc....

I'd like to do a search for the top 5 documents in each category. I
can do this with a separate search for each facet, but it seems like
there would a way to combine the search. Is there a way?

That is, if the user searches for "my search", I can now search for it
with the facet of "physics" and rows=5, then do a separate search with
the facet of "chemistry", etc...

Can I do that in one search to decrease the load on the server? Or,
when I do the first search, will the results be cached, so that the
rest of the searches are pretty cheap?

I think that what you want is FieldCollapsing:

http://wiki.apache.org/solr/FieldCollapsing

For example
&q=my search&group=true&group.field=subject&group.limit=5

Test it to see if that is what you want.

Thanks
