Hi all,

I'm looking for an easy way to index documents containing an email field  
and searching for them using pre- and postfix wildcard queries (something  
similar to SQL: WHERE email LIKE '%search\_term%').

One way may be using the uax\_url\_email tokenizer but it seems that in this  
case prefix wildcards aren't supported. Is that true?

As an alternative I thought of using a not\_analyzed field to store the  
email adress and query them with a something like an ignorecase flag...?

Regards,

Abid
