 It's based on my observation, that over the years, a number of us in the community have done
some pretty cool things using Lucene that don't fit under the core premise of full text search.
 I've got a fair number of ideas for the talk (easily enough for 1 hour), but I wanted to
reach out to hear your stories of ways you've (ab)used Lucene and Solr to see if we couldn't
extend the conversation to a bit more than the conference and also see if I can't inject more
ideas beyond the ones I have.  I don't need deep technical details, but just high level use
case and the basic insight that led you to believe Lucene could solve the problem.
