Robert Muir commented on SOLR-2272:
-----------------------------------

Its the same argument we have here, all over again. If we could actually freely refactor stuff
from solr into lucene (e.g. spatial search functionality, which seems like some lucene users
MIGHT just want), then it really doesn't matter where it goes.

Sure its "ideal" if the patch puts the core functionality in lucene and the solr bits in solr,
but it would still be "great" even if the patch starts totally solr, and there is at least
the hope in the future of refactoring (if someone is willing to do the work).
