I expect google to ignore what I searched for and change it to something more commonly found. Even setting it to Verbatim did not yield a correct first result:
Kagi used to be so so so good at accurate searching and in the past week or two it really seems like its sadly slipping.
I would say that it probably is to assume a correct spelling.
But when you have one set of results that are far more common (a couple orders of magnitude probably) it’s reasonable to go with the more popular result.
