I noticed that when trying to find articles using the search form I dont always find what I am looking for.

for example:

if I search for the word info it will find articles with info and information however if I search for transact I dont find articles with transaction in it.

Kinda wierd ..

also is there any extension where the search results will display a "Did you mean: */transaction/* http://www.google.com/search?hl=en&q=transaction&spell=1" similar to google?
