Very interesting. When I started using Google as an undergrad (circa 1999), I remember using the "+" character in searches, since that was standard procedure for searching linked strings before the age of Google Empire; I distinctly remember Google popping up warnings: "this '+' character is NOT necessary in searches" . . .. Weird.
