Xapian discuss - Jun 2011 - Higher weight on exact matches when doing wild card search

Hi

I am working on a search which needs wild card support. Unfortunately 
this makes some searches for short words return bad results, because 
they match a lot of words that aren't related to what the user actually 
wants. I'm wondering if there's a good way to make specific matches get 
a higher weight than longer words?

Example: when search for car, documents containing car are more relevant 
than documents only containing carcass.

Thanks.

Could you parse the query twice, once with wildcard turned on, once without, and
adjust the relative weighting of the two queries when you combine them?
