Subject [jira] Commented: (LUCENE-2167) Implement StandardTokenizer with the UAX#29 Standard
Date Mon, 10 May 2010 18:38:32 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865857#action_12865857
] 

Marvin Humphrey commented on LUCENE-2167:
-----------------------------------------

I find that it works well to parse URLs as multiple tokens, so long as the
query parser tokenizes them as phrases rather than individual terms.  That
allows you to hit on URL substrings, so e.g. a document containing
'http://www.example.com/index.html' is a hit for 'example.com'.

Happily, no special treatment for URLs also makes for a simpler parser.

> 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.
