I clicked Search in the upper right corner. I entered "Windows 8" in quotes. The response is "The search term you specified (8) is under the minimum word length (2) and therefore will not be found. Please make this term longer. If this term contains a wildcard, please make this term more specific." Wassup wit dat?
Technically "Windows 8" is a phrase made up of two words. The number 8 is considered a word, which is lower than the 2 character minimum required, hence the error.
