Can someone explain to be what the state of Solr/Lucene is... didn't they
recently combine?

I know I am running version 1.4 but I keep seeing version numbers out there
that are 3.0, 4.0??? Can someone explain what that means.

Also is the state of trunk (1.4 or 4.0??) "good enough" for production use?

Thanks!

Yes, it started in March.  Development is combined (committers, dev
list, etc), but separate downloads and user lists will remain.

Lots of other stuff has changed.  For example, trunk is now always the
next *major* version number.
So the trunk of the combined lucene/solr is 4.0-dev

There is now a branch_3x that is like trunk for all future 3.x releases.

The next version of Solr will probably be 3.1, and it's unlikely there
will ever be a 1.5 released.

Yes, Lucene/Solr aims for a "stable" trunk (runtime stability, not API
stability).  Plenty of big companies use trunk since they need recent
features.  Just be sure to test well (good advice even if working off
of officially released versions).

Wait.. what? Now, im more confused

What version is (http://svn.apache.org/repos/asf/lucene/dev/trunk/)? Im
guessing its 4.0-dev but then where does 3.1 fit in?

Say I am running 1.4 and want to upgrade, which version should I use? If I
want to use a patch that has a fix version of 1.5 which should I be using?
(https://issues.apache.org/jira/browse/SOLR-1316).

Thanks again

Patches in SVN are not official and not guaranteed to work (or even
patch correctly) to any version.
You need to look at the specific patch to see what svn path it is
relative to, and how old it is.
