Not sure about documented examples, but I often find the unit tests (in src/test of lucene's CVS) to be very useful for examples but I didn't see any for what you are looking for.
Basically, query parser builds up a vector of BooleanClause objects then loops over those on a BooleanQuery object calling add(BooleanClause). I agree JavaCC isn't really simple to follow, but there is a lot of plain java in there that does the parts you are interested in and if you build the .java file and ignore the token parsing stuff, you can look at in your favorite java IDE. What you can do is cast the query you get from QueryParser to a BooleanQuery (that is the only type of Query that QueryParser will return) then create your WildcardQuery or any other queries you need that you didn't get in the query string and add them as clauses to the BooleanQuery using add(Query query, boolean required, boolean prohibited). I don't know how query combine works (never used it), but the javadoc comment leads me to believe it is not what you are looking for and a bit of poking around in the sources gives me the same impression.

Is there an example anywhere on how I might be able to build such a Query? QueryParser isn't really all that simple since it's built with JavaCC. What might be ideal for me is if I can continue to use the highlevel interface to build the main query (ie use it to parse my query string and return me some kind of Query - BooleanQuery, TermQuery, etc) and then build a WildcardQuery by hand and "combine" the two together? For example, is it as simple as calling Query.combine() to combine the two? Is there a better way? Is there a documented example like this?
