How much Lucene 4.0 capability is NOT in Solr 4.0?
I was perusing email from this list and came across LUCENE-4069. If it
is as good as it says, it looks like a fit for a couple of the fields in
my index.
I will admit that I don't entirely understand all of what's being said
regarding codecs, postings, and other such terms, but because I run a
distributed Solr index, I do understand that not all of Lucene's
functionality is available in Solr. My question: How much of all the
new bells and whistles in 4.0 will be available in Solr without custom
coding? In this specific instance, I would like to be able to use
LUCENE-4069, but my question is more general than that -- will it be
possible to take the official Solr 4.0 (or 4.1, or 4.2) download and
specify codecs and other details on a per-field basis?
Thanks,
Shawn

"the codec stuff is all useable from solr out of the box"
Is there any doc for that, I mean setting codec config settings from the
Solr level?

DocValues (CSF) are not yet supported in solr:
https://issues.apache.org/jira/browse/SOLR-2753
There is not yet a plan for how this would be incorporated.
As Robert already said, the codec stuff is all useable from solr out of the
box

I have never used trunk/4x, only Solr 1.4.1 and 3.x, and my only
exposure to test internals has been adapting existing tests for
SOLR-2906 and SOLR-3393. Now that branch_4x has been created, things
will begin to stabilize. When my schedule clears up a bit, I will do
testing with the new branch. I am looking forward to the new version
and understanding all the improvements.
I'm not terribly worried about backwards compatibility. Because of the
javabin version change in 3.1, I abandoned replication in favor of two
independent indexes that are both kept up to date. Now I can upgrade
and rebuild one index without affecting the other.
Thanks,
Shawn

Maybe you are confused... you can already do this (for over a year).
See the tests.
Keep in mind that customizing the index format in this way is expert,
e.g. we don't provide index backwards compatibility for it across
releases, etc etc.
