I've quickly looked, but haven't seen this to be the case. The new query parser framework uses the same JavaCC grammar and creates intermediate objects that eventually create Lucene Query objects. >From an IBM perspective (where this parser came from), it makes it easier to add a new syntax because they have multiple back-ends (Lucene being one, probably OmniFind or other proprietary search engines being others). But from the Lucene perspective, there is only Lucene as a back-end. So if you want to try and extend the syntax of the lucene query parser, it still seems to come down to hacking on the JavaCC grammar (the hard part). -Yonik http://www.lucidimagination.com
