Need improvement

How can I search for a word when I dont know how to spell it. There should be a way that the app could recognize what Im trying to type. There are words in German and French that have some special letters, and the app cant find the word unless you know how the word is spelled!
Ä,ë,ü , etc. how am I supposed to know? This is supposed to help you
