Subject [jira] Commented: (LUCENE-2167) Implement StandardTokenizer with the UAX#29 Standard
Date Mon, 10 May 2010 13:59:48 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865765#action_12865765

Robert Muir commented on LUCENE-2167:
-------------------------------------

bq. One other thing, Robert: what do you think of adding URL tokenization?

I think I would lean towards not doing this, only because of how complex a URL can be these
days. It also
starts to get a little ambiguous and will likely interfere with other rules (generating a
lot of false positives).

I guess I don't care much either way, if its strict and standards-based, it probably won't
cause any harm.
But if you start allowing things like http urls without the http:// being present, its gonna
cause some problems.

> 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.
