There currently obviously is no search term adaption taking spelling into acccount. Like general purpose search engines do. You need to enclouse it in " to only find sites with the wrong spelled name "baldis basics plus". If you search baldis basics plus it will not even ask if you misspelled the name and just search for baldi's basics plus, unlike balds basics plus, where it will search for the correct one too, but remind you that there might be a spelling error.
While there might not be a fuzzy approach be needed, ignoring the peculierites of some letters and concatenations should be mapped for the database searching. The url name of the game had to excluce the ', did it not?
I wonder how it is for names containing letters like these: â é Ø and so on. Or whitespace. I know there is even a bug with _ appearing in names, or at least tags. It maps to -, even though it is an allowed character.
