Hi Nathan!

Glad to have you on this list!

I could try, but I'm not a very good coder (maybe too lazy to learn more 
lo-level stuff ;)

Cool!
Now make a backup of your hard drive so we'll not loose our fast search ;)
Does this also include searches with large result sets?

This is great!

Done. Sent an answer to yor eMail.
