Lucene thoughts

Team,
    I was thinking some about how to enable searching throughout JLCP 
and allowing each new module that is dropped in to also be searched.  
One thing we need is that each HibernateDAO needs to have an abstract 
method, getAllData() which returns a list of all the data for that 
model.  That's a start.  From there, we still need to know how to index 
everything.  Each item will be unique.  Do we try to just index and 
search certain things, with an indexer for each module?  For example, we 
have to search a different field for content in links and forums and 
calendars.  How do we deal with that?  Our biggest issue is enabling the 
system to search all modules, not just the core.  I would love to hear 
everyone's thoughts on this.
