Re: Fun in google!!!!
It has to do with parsing. When you type in a search query, Google will find the individual keywords, looking for a space or other seperator character. Therefore "Fun with Google" is parsed into the query (in English): ?hl=en&q=fun+with+google.
Your experiment shows emperically, that Google uses a field length of 128 characters. 128 "a"'s have no seperator, but are WITHIN the 128 character limit, so it parses out as a word of 128 a's. A string of 129 characters cannot parse at all, as it exceeds the field length, and has no seperators, so the result of the parsing is null.
How many times did you try before discovering this?
