Subject Re: Solr 1.4.1 compatible with Lucene 3.0.1?
Date Tue, 12 Apr 2011 00:52:03 GMT
Hi,

I only read the short story. :)
Note that you should post questions like this on solr-user@lucene list, which is 
where I'm replying now.

Since you are just starting with Solr, why not grab the recently released 3.1?  
That way you'll get the latest Lucene and the latest Solr.
