how can I return function results in my query?
I want to be able to run a query like idf(text, 'term') and have that data
returned with my search results. I've searched the docs,but I'm unable to
find how to do it. Is this possible and how can I do that ?

Haven't tried it, but it definitely should!

Nice! Will SOLR-1298 with aliasing also work with an external file field since
that can be a source of a function query as well?

In trunk, there's a very new feature called pseudo-fields where (among
other things) you can include the results of arbitrary function
queries along with the stored fields for each document.
fl=id,idf(text,'term'),termfreq(text,'term')
Or if you want to alias the idf call to a different name:
fl=id,myidf:idf(text,'term'),mytermfreq:termfreq(text,'term')
Of course, in this specific case it's a bit of a waste since idf won't
change per document.

Jason,
Solr cannot add results of functions to the resultset for now. I don't know
about a ticket (but i'd think there is one) but it's also highly desired in
returning distances in spatial queries. Check Jira if you need to know more.
Take care, debugQuery can add significant delay. If you need idf frequently
then consider tvc.

Markus,
Thanks for this info, I'll use debugQuery to test for now. It seems strange
that I can't have arbitrary function results returned with my data. Is
this an obstacle on the lucene or solr side?

Ah, function results are not returned in the result set. You must either use
debugQuery to get the value or the TermVectorComponent to get idf for existing
terms.

I have never used Relevance Functions but there is an example [1] in the wiki where result of the function query is reflected into score. Then in order to get the computed function query it uses &fl=*,score.

Ahmet, that doesnt return the idf data in my results, unless I am
doing something wrong. When you run any function you get the results
of the function back?
Can you show me an example query you run ?
