Will misspelled names on persons lead to no hits on the search?

This depends on the settings you are using. There are two modes for search on names; "Exact" and "fuzzy".

In exact mode all names must be written exactly like how the persons name says on the list. "Ola Nordman" will match towards "Per Ola Nordman", as both names used in the search are in the list. Furthermore, the order of the names does not impact the results. However, "Ola Norman" will not provide any matches, as "Norman" and "Nordman" are unequal. 

If the fuzzy mode is used, the latter search will still provide results. Guidance on how to use these two modes and interpret the results are available. The use of fuzzy mode will lead to more fake positives.
