As I promised earlier, in order to leverage 3rd party regex
implementations I have removed the (Span)RegexQuery code from the
core and into contrib/regex. The implementation is vastly
different in that I've abstracted out the regex implementation and
provided one for JDK 1.4 java.util.regex and Jakarta Regexp.
Jakarta Regexp has a nice feature of being able to provide the
static prefix in order to short-circuit term enumeration. In my
project, I've created a custom implementation that uses Jakarta
Regexp for the prefix but java.util.regex for the actual matching
in order to have the best of both worlds.
I may have over-engineered it a bit, though I'm not sure. I'm in
the process of documenting beyond just the unit tests, and likely
will also document how to use regex queries along with term
rotation in order to really minimize term rotation - though I'm
still working on this feature in my current project.
Oops... typo.... "to really minimize term _enumeration_"
