Steven Rowe commented on LUCENE-2745:
-------------------------------------

bq. steven, check out the link at the bottom of that article.

Yup, did that.

bq. especially the top... it explains the use in the language, particularly to block cursive joining for prefixes, suffixes, compounds. we split on this and the affixes are in the stoplist 

Um, like I said, Persian uses ZWNJs as display hints, not as word separators.

According to the [ICU web demo|http://demo.icu-project.org/icu-bin/ubrowse?go=200C], ZWNJs have the \p{Word_Break:Extend} property, so the Lucene UAX#29-based tokenizers will *not* split on this char.

What am I not getting?

> 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
