I believe the usual solution is to have a separate field on the same
document for display purposes (I am assumming you are trying to display
the values of the indexed field) that is not stemmed. The tradeoff is
in disk space, of course.

Okay, I've taken Grant's advice and aggregated the TermFreqVector's for
each term in the applicable field. It works quite well, there's just one
glitch.
Some words like "party" and "picture" appear as "parti" and "pictur".
I am
using the SnowballAnalyzer, I suspect that's what's changing the words.
Short of maintaining a second index using a different analyzer, does
anyone
have any ideas?

Subject: Re: top n words within a results set?
You could use term vectors to accomplish this. Get your hits for the
website, then load the term vector for the field containing the
keywords and add up the frequencies

Hello,
Is it possible to retrieve the top 'n' most often appearing words
within a search criteria? I've seen the High Frequency Terms code in
the sandbox but it works across the whole index.
To put this question into context: We're developing website that
hosts a user's photo website. Searches can be specific to a
particular user's website or be performed globally across one, many
or all websites. I've accomplished this with a field in the index
called website. What I'd like to do is give each user the top ten
words that appear on their website.
Thanks,
Chris Brown
