Subject [jira] Commented: (LUCENE-2167) Implement StandardTokenizer with the UAX#29 Standard
Date Mon, 10 May 2010 21:00:31 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865921#action_12865921

Steven Rowe commented on LUCENE-2167:

bq. A filter that breaks URL type tokens into their components, and then adds them as overlapping
tokens, or replaces the full URL with the components, should be easy to write, though.

Not sure, for this to really work for non-english, it should recognize and normalize punycode
representations of international domain names, etc.

So while its a good idea, maybe it is a can of worms, and better to leave it alone for now?

Do you mean URL-as-token should not be attempted now?  Or just this URL-breaking filter?

> 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.
