Thanks for saying.   I thought as soon as I sent it that my motivation might 
just be to brag that I know something that long-time Solr folks like you might 
not.   I actually know so very little, not just about how Lucene works, but how 
to make Solr solve concrete problems beyond the simple.   I feel like just now 
am I really upping my game; hopefully it continues.

Daniel,

Thank you for the very concrete example. That is helpful.
