Global Search - find similar results

As of now, searching in the awesome bar only returns records which contain the exact same substring in some field. This is an issue for us since sometimes documents get missed when the search was spelled incorrectly, or has a special character (like ø or ö) while the record does not (or vice versa).

Is there a way to improve the global search, so it will also find records with strings that are similar? For example searching for “test customer” should also return the result “testcustomer”.
