Why `toUpper` in case insensitive search?

Just curious if there was a reason case insensitive searching was done with `toUpper` instead of `toLower`? In some of my own testing (using multi-word search), searching for "God so loved" would take 3.5 seconds using `toUpper`, but only 0.5 seconds for `toLower`. I'm guessing because fewer characters are needing to be converted.
