Lucene Query Parser

Hi,

this is a bit off-topic because it's not directly incorporated to 
jahia itself. But maybe anyone knows a answer to this:

Is there a query interpreter interface/api in lucene? I'm working 
on a highlighter for jahia currently and my only remaining problem 
is to parse the searchstring (which is no problem to retrieve) so I 
can decide which strings I have to "colorize". It's easy for terms 
like "foo AND Bar" but not every search query is that easy.

Best Regards
