It's got some pretty big changes.

api breaking changes coming, then perhaps the next couple 1.x revisions should be taken to
start cleaning up and preparing for a major version bump. So, I would agree that, unless there's
a really compelling reason to switch to Lucene 3.x, it might be best let a little dust settle
on 2.9.

I think we are going to want to support flexible indexing within a pretty reasonable time
frame after it is available.  Also note, there are some fairly big Solr changes in the pipeline
at this point:
1. Spatial support, which will change/add some significant general purpose capabilities to
2. Significant new distributed capabilities for both indexing and searching
3. And of course a fair number of other things.  

Agreed, though, on the fact that we should cleanup in prep for 2.x, so we may want to shoot
for a 1.9 first.
