I'm kind of confused about Solr development plans in general,
highlighted by this thread.
I think 1.4.1 is the latest officially stable release, yes?
Why is there both a 1.5 and a 3.x, anyway? Not to mention a 4.x? Which
of these will end up being a stable release? Both? From which will come
the next stable release?

The devs try and keep both the 3 and 4 (trunk) branches stable in the
terms you are talking about at all times. But bear in mind that more
radical changes will tend to hit trunk, probably making it by definition
less stable than 3. But it all depends - you might find a worse bug on
the 3 branch!
A lot of the major changes on both branches have been fairly well tested
up to this point IMO. I really think both are viable options if you
properly test your deployment ahead of time.
One large point though - when you jump on trunk as opposed to 3, you are
more likely to be bitten by an index format change that makes upgrading
an index a pain without a reindex. I think this risk is much greater on
trunk - though when a lucene codec covers all index files, the whole
problem should be heavily mitigated at the least.
It's usually best to reindex anyway, but so painful for some, I guess
there is sometimes really no choice.

Hi,
I've successfully downloaded and deployed 1.4.1, which is fine except it
doesn't support the spatial search stuff. I tried installing LocalSolr but
came to a bit of an impasse when it appeared to index stuff but didn't
return any results (and then I saw the last commit to the LocalSolr
repository was Dec last year so decided that was probably out-of-date
anyway).
So, if I want the spatial search support it appears there are 2 candidates.
Either the 1.5 or the 3.1 branch and my question is, which one is best for
me to use? I guess the answer to this question is driven by how up-to-date
(with respect the spatial search stuff) and stable 1.5 is (I notice the last
commit is a little over 6 months ago) and how close to stable the 3.1 branch
is.
This is ultimately for a production system so I'm not too keen on "winging"
it with an unstable version, but I'd really like to take advantage of the
spatial search stuff if possible.
As an ancillary question, does anyone know how stable the 3.1 branch is and
how close the dev team feel they are to a release? I guess "it's done when
it's done" but a general idea would be quite helpful.
Thanks in advance.
Mike.
