Steven Rowe commented on LUCENE-2167:
-------------------------------------

bq. i would prefer we switch the situation around: make UAX#29 'standardtokenizer' and give the uax#29+url+email+ip+... a different name.

UAX29Tokenizer does not have email or hostname recognition.  StandardTokenizer has long had these capabilities (though not standard-based).  Removing them would be bad.

> It would be really nice for StandardTokenizer to adhere straight to the standard as much as we can with jflex. Then its name would actually make sense.
> Such a transition would involve renaming the old StandardTokenizer to EuropeanTokenizer, as its javadoc claims:
> bq. This should be a good tokenizer for most European-language documents
> The new StandardTokenizer could then say
> bq. This should be a good tokenizer for most languages.
> All the english/euro-centric stuff like the acronym/company/apostrophe stuff can stay with that EuropeanTokenizer, and it could be used by the european analyzers.
