There's the literal aspect which brain dead, but very fast processing, algos deal with. How many ways can the ampersand be coded? Quite a few. And let us not get started on endash, emdash and ellipses!

"Briggs & Stratton" doesn't necessarily mean the same thing as "'Briggs' and 'Stratton'."
(Mind you, a lot of people--including me--are as likely to type "briggs and stratton" as they are to type "briggs & stratton" if they're looking for information on small engines for lawn mowers and the like. I wonder if search engineers spend much time agonizing over the sweet spot between literal correctness and adjusting for user behavior?)
