Search feature hack "Did you mean"

[Scandal]

Hello!

Is there any hack for a feature as "Did you mean: x" on vBulletin search page?

It is a feature on search engines [eg YouTube - Google etc] for similar words [usually, it appears the spelled word which has been used on a post].


Thanks and sorry for my bad english, I hope that you'll understand what I mean. :)
