<section name="Purpose">
<p>
This document describes the list of tasks on
the plates of the Lucene development team. Tasks are assigned into
two
categories: core or non-core.
</p>
</section>
<section name="About Core vs. Non-Core Development">
<p>
Currently the Lucene development team is working on
categorizing change requests into <b>core</b> and <b>non-core</b>
changes.
</p>
<p>
Core changes would entail a change to the search engine
core itself. From Doug Cutting:
<blockquote><i>
"Examples include: file locking to make things
multi-process safe; adding an API for boosting individual
documents and fields
values; making the scoring API extensible and public; etc."
</i></blockquote>
</p>
<p>
Non-core changes would not affect the search engine
itself, but would consist instead of projects or components that
would
make useful
additions to the core framework. Again, from Doug
Cutting:
<blockquote><i>
"[Examples] include: support for more languages; query
parsers; database storage; crawlers, etc. Whether these
belong in the
base distribution is a matter of debate (sometimes hot). My
rule of
thumb for including them is their generality: if they are
likely to be
useful to a large proportion of Lucene users then they
should probably go
in the base distribution. Language support in particular is
tricky.
Perhaps we should migrate to a model where the base
distribution
includes no analyzers, and supply separate language
packages."
</i></blockquote>
</p>
<p>
Change requests will be categorically defined by the
development team (committers) as core or non-core, and a committer
will
be assigned responsibility for
coordinating development of the change request. All
change requests should be submitted to one of the Lucene mailing
lists, or
through
the <a href="http://issues.apache.org/bugzilla/";>Apache
Bugzilla</a> database.
