Subject [jira] Commented: (LUCENE-1702) Thai token type() bug
Date Fri, 19 Jun 2009 17:10:07 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721884#action_12721884

Robert Muir commented on LUCENE-1702:
-------------------------------------

Steven, thanks for the information, and the range representation sounds interesting.

So I'll let others comment if they want it to be fixed pre-1.5.0, in this case we could define
macros in jflex that represent what we want, with comments indicating how they will be defined
in the future jflex.
Either way, a specific unicode version should be selected, with the macros defined from that
unicode version or that unicode version specified to jflex 1.5.0... unicode 5.1 sounds good
to me :)

The matchVersion could be used to ensure that back compat always works.

> While adding tests for offsets & type to ThaiAnalyzer, i discovered it does not type
Thai numeric digits correctly.
> ThaiAnalyzer uses StandardTokenizer, and this is really an issue with the grammar, which
adds the entire [:Thai:] block to ALPHANUM.
> i propose that alphanum be described a little bit differently in the grammar.
> Instead, [:letter:] should be allowed to have diacritics/signs/combining marks attached
to it.
> this would allow the [:thai:] hack to be completely removed, would allow StandardTokenizer
to parse complex writing systems such as Indian languages, and would fix LUCENE-1545.
