Unfortunately, due to technical constraints we cant allow anything under 3 characters. If you want to be a geek about it, basically it indexes all the words, so to index 2-3 char words, you can imagine would return an aweful lot to index.
As Stew says, use google and include the site name, works 9 times out of 10 (they have more space and power to index 2-3 char words)
cheers for the explanation fair enough. i'll just continue to google. i suppose that's why alot of sites have google powered searches.
reminds me of indexing in windows xp, what a pile of cr*p that was.
