LIA/2 suffers the same false dichotomy, and it drives me crazy there
too: we put all "contrib" packages in a different chapter, even though
it'd make much more sense to cover all analyzers in one chapter, all
queries in one chapter, etc.
I find myself cross-referencing over to TrieRangeQuery in Chapter 8,
from LIA's search chapter (Chapter 3), and it's awkward.

I agree: revamping the web-site for a better top-down introduction of
Lucene's features should be part of 3.0.
And I don't think the sudden separation of "core" vs "contrib" should
be so prominent (or even visible); it's really a detail of how we
manage source control.
When looking at the website I'd like read that Lucene can do hit
highlighting, powerful query parsing, spell checking, analyze
different languages, etc. I could care less that some of these happen
to live under a "contrib" subdirectory somewhere in the source control
system.

Could we, instead, adopt some standard way (in the package javadocs)
of stating the maturity/activity/back compat policies/etc of a given
package?

So I think the beginnings of a rough proposal is taking shape, for 3.0:
1. Fix web site to give a better intro to Lucene's features, without
exposing core vs. contrib false (to the Lucene consumer)
distinction
2. When releasing, we make a single JAR holding core & contrib
classes for a given area. The final JAR files don't contain a
"core" vs "contrib" distinction.
3. We create a "bundled" JAR that has the common packages
"typically" needed (index/search core, analyzers, queries,
highlighter, spellchecker)
