Mark Miller commented on LUCENE-966:
------------------------------------
I think it is important that we do not modify the StandardAnalyzer and that
this improved version has results identical to the original. I believe that the
StandardAnalyzer is pretty heavily used -- these performance increases could
give many users huge gains. By changing this Analyzer at all we will be forcing
users to effectively lose terms in their indexes if they want to upgrade core
Lucene for use on an older index.
I think any enhanced StandardAnalzyer should probably be released as a new
Analyzer. This one should mimic the old though, as the performance gains will
be very beneficial to a lot of current users.
