Hi Geoffrey,

Thanks for moving this discussion forward. There is already some 
discussion of lucene integration and a fair amount of hand-waving in 
http://issues.apache.org/jira/browse/DERBY-472 and 
http://wiki.apache.org/db-derby/LuceneIntegration In particular, the 
wiki page poses 3 use-cases for this integration: loose coupling, 
moderate coupling, and tight coupling. Once we look under the hood, some 
of these use-cases may not make sense. Am I right in assuming that you 
are interested in tight-coupling?
