[Dev] Lucene search

[Brett Wooldridge]

Highlighting is possible.  But maybe not possible in 2007.09.  Lucene
provides a Highlighter framework, and some default implementations ‹ like an
HTML highlighter.  However, since we don¹t display configs as HTML this
would be of little use.  However, the framework is there for us to wire up
our own highlighter logic, which presumably would record byte-offset
start/end highlight pairs or some such.  It is possible that Lucene already
has this, but a quick inspection did not turn it up.

So short answer: yes, possible (and supported) with Lucene.
