Hi Christian,
That syntax is not entirely correct.
Search in the mailing list for "*term" or suffix queries
a few months ago I submitted the correct grammar that enables
suffix queries.
Best,
Sergiu

I have found in the QueryParser.jj those lines of comments:

// To:

So as indicated I changed my line to the second option but it didn't solve
the problem I still getting the lexical error. Do I have to do something
special to this .jj file or is it read when the QueryParser.java file is
compiled?
Cheers
Chris

Hi,
I modified the analyzer (it is now vegetarian and won't eat numbers

This is by-design "issue" with QueryParser (to avoid WildcardQuery's
from being created that run through every term in the index). It is
the way the grammar has been defined. You would need to build your
own QueryParser to change this behavior. The relevant QueryParser
grammar piece is this (from QueryParser.jj):
| <WILDTERM: <_TERM_START_CHAR>
(<_TERM_CHAR> | ( [ "*", "?" ] ))* >
