> 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
