Subject [jira] Commented: (LUCENE-2167) Implement StandardTokenizer with the UAX#29 Standard
Date Sat, 12 Jun 2010 15:45:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878276#action_12878276

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

by the way Steven, one alternative idea i had before for this was to have a jflex or rbbi-powered
charfilter for sentences.

you could provide it with string constants in the ctor to replace sentence boundaries, to
add position increments just add these to your stopfilter.

the advantage to this would be that you could use it with other tokenizers by using this special
token (i guess just be careful which one you use!).

sorry to stray off topic a bit with this, but i think its sorta a missing piece thats relevant
and becomes more important with ComplexContext :)

> 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.
