I dunno whether its done for a security reason, but one thing that I find annoying with the search fuction is that you can't enter a word less that 3 charecters.

I understand it gets rid of words such as the and to and other meaningless words but its a pain when you search for things like "xp security" or "xp user accounts" basically anything with the version of windows in it.....

Thats probably why negatives searchable tutorial index is gonna be really useful...

Heres the delightful message if you havent seen it -

The search term you specified (xp) is under the minimum word length (3) and therefore will not be found. Please make this term longer.
If this term contains a wildcard, please make this term more specific.
