serverDefined can (obviously) only be ignoreCase or respectCase, as it's
a boolean option.  Either you ignore case or you don't.

So it's:

+ I care which:
     * I want case ignored       (ignoreCase)
     * I want case respected     (respectCase)
+ I don't care which             [nothing in query]
