Yes, with a little bit of work, as there is nothing out of the box
for it.
If you store term vectors (or re-analyze the document) you can use
the sample code from my ApacheCon 2005 talk (http://www.cnlp.org/
apachecon2005/, which also covers how to use TermVectors) OR you can
try implementing the new TermVectorMapper functionality in the trunk
version of Lucene.
