[jira] Commented: (LUCENE-2745) ArabicAnalyzer - the ability to
recognise email addresses host names and so on
[ https://issues.apache.org/jira/browse/LUCENE-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929362#action_12929362 ]
Steven Rowe commented on LUCENE-2745:
-------------------------------------
I think that ArabicLetterTokenizer, which is the tokenizer used by ArabicAnalyzer, is obsolete (as of version 3.1), since StandardTokenizer, which implements the Unicode word segmentation rules from UAX#29, should be able to properly tokenize Arabic. StandardTokenizer recognizes email addresses, hostnames, and URLs, so your concern would be addressed. (See LUCENE-2167, though, which was just reopened to turn off full URL output.)
You can test this by composing your own analyzer, if you're willing to try using using as-yet-unreleased branch_3X, from which 3.1 will be cut (hopefully fairly soon): just copy ArabicAnalyzer class and swap in StandardTokenizer for ArabicLetterTokenizer

> Key: LUCENE-2745
> URL: https://issues.apache.org/jira/browse/LUCENE-2745
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/analyzers
> Affects Versions: 2.9.2, 2.9.3, 3.0, 3.0.1, 3.0.2
> Environment: All
> Reporter: M Alexander
>
> The ArabicAnalyzer does not recognise email addresses, hostnames and so on. For example,
> adam@hotmail.com
> will be tokenised to [adam] [hotmail] [com]
> It would be great if the ArabicAnalyzer can tokenises this to [adam@hotmail.com]. The same applies to hostnames and so on.
> Can this be resolved? I hope so
> Thanks
> MAA
