Searching for a person with parameter aa or tr (just the ones I've found, could be more) results in a 500 Server Error. Have been testing the same query for weeks and have not had similar results with other input values. Full query: https://api.themoviedb.org/3/search/person?api_key={key}&language=en&query=tr
