Ah, okay... some people call that "prospective" search. In any case, there 
is no direct Lucene support that I know of.

There are some references here:

Subject: Re: Re: Wildcard in a text field

For instance, I have a list of tags related to a text. Each text with
its list of tags are put in a document and indexed by Lucene. If we
consider that a tag is "buddh*" and I would like to make a query (e.g.
"buddha" or "buddhism" or "buddhist") and find the document that contain
"buddh*".

Thanks,
