Solr version in Solrcas
Hi all,
Going through changes in UIMA-2109 [1] to update dependencies of UIMA Addons
projects to latest versions (where possible) I see we can safely update
Solrcas to use the just released Solr 3.1.0 instead of the previous 1.4.1.
Since there are significant changes in the Lucene index being written by
Solr in those versions 1.4.1 indexes can be not compatible with indexes
written with Solr 3.1.0.
So my question is, should we upgrade to use Solr 3.1.0 now and have Solrcas
2.3.1 run on top of it to have the nicest software available at this time or
let this change happen for 2.3.2 and make Solrcas more compatible with
existing Solr platforms?
Thanks,
Tommaso

Nice, then we really should do it now.

Yes from an API point of view it's backward compatible till Solr 1.3.

It might be difficult to update from Solr 1.4 to Solr 3.1 in some cases.
Is the Solr 3.1 client we would then use backward compatible with a Solr
1.4 server?
Anyway I am +1 to do the change now, we did not release anything
and do not have to care for backward compatibility.
