Using Lucene to search for email addresses

Question

I want to use Lucene (in particular, Lucene.NET) to search for email address domains.

E.g. I want to search for \"@gmail.com\" to find all emails sent to a gmail add

Answer 1

There also is setAllowLeadingWildcard

But be careful. This could get very performance expensive (thats why it is disabled by default). Maybe in some cases this would be an easy solution, but I would prefer a custom Tokenizer as stated by Judah Himango, too.
