upgrading to lucene 2.3
I have heard that upgrading to lucene 2.3 in Solr 1.2 is as simple as
replacing the lucene jar and restarting. Is this the case? Has anyone
had any experience with upgrading lucene to 2.3? Did you have any
problems? Is there anything I should be looking out for?
Thanks
Rob

See:
https://issues.apache.org/jira/browse/SOLR-330
https://issues.apache.org/jira/browse/SOLR-342
for various solutions around taking advantage of Lucene's new
capabilities.

Text analysis may be slower since Solr won't have the changes to use
the faster Token APIs.
Indexing overall should still be faster.
Querying should see little change.

I did the same:
Stopped SOLR-1.2, replaced Lucene jars, started SOLR-1.2
No any problem.

ok, and to do the change I just replace the jar directly in
sorl/WEB_INF/lib and restart tomcat?

Solr Trunk is using the latest Lucene version. Also note there are a
couple edge cases in Lucene 2.3 that are causing problems if you use
SOLR-342 with lucenAutoCommit == false.
But, yes, you should be able to drop in 2.3, as that is one of the
back-compatible goals for Lucene minor releases.
