pseudo-relevance feedback enhancement

Hi,

A while back I wrote some code to implement automatic query expansion in Lucene.
Now I ripped off the application specifics and put it in more or less "test-case
style" in the attachment. Apart from the sources and classes, it contains a tiny
index consisting of sample data I got from the Lucene FAQ. Almost too small to
be meaningful, but with the sample query you'll get at least a different number
of hits.

I made some arbitrary decisions on where to put the classes. Mainly they ended
up in the lucenesandbox-package and should have unique names, hence not
overwriting anything.

The comments in the source were chiefly written to illustrate the flow to
not-so-experienced Lucene users/java programmers. You might find self-evident
what they describe.

Please refer to the "quick start" section in the readme file to get
things going (should be really quick).

If you have any questions or comments, I'll appreciate your feedback. 

Best regards,

Rene Hackl
