I like the idea of replacing the internal regexp in favor of a more fully
developed regexp evaluator. The goal should be to get rid of the weaker
regexp module. A question I don't know how to answer is which is the best
replacement. As Thorsten points out, ideally the replacement should be
enabled for localization and transliteration - again more stuff I don't
understand well at all.
However, looking at textsearch.cxx in Open Grok --
-- can see this comment before the various types of calls to a search
// use transliteration here, but only if not RegEx, which does it different
One can also see other exclusion of the regexp search algorithm from the
transliteration search prep and search result code in textsearch.cxx around
the calls to the search routines, but I'm not absolutely sure that exclusion
is complete. If the regexp search truly *never* uses transliteration then
the swap out will be simpler and the change-over may actually enable
transliteration. I haven't looked at the internal code of the regexp -
perhaps it 'does it's own thing' internally for transliteration...
