Text search fails for partial word e.g. "Zertifikat" so "Zertifikatskurs" is not found

In german words are often aggregated, "Zertifikatskurs" is a conjunction between "Zertifikat" (certificate) and "kurs" (course). We need to be able to find the results for the aggregate if we search for all of its parts.

In the case i want to search for the resource Zertifikatskurs "Forschungsdatenmanagement für Studierende": Spring School 2023 der Landesinitiative für Forschungsdatenmanagement in Brandenburg the search should work for zertifikat and kurs. Currently it works for kurs, but fails for zertifikat.

As i understand using "zertifikat*" as search term works. So maybe a search for "searchterm" needs to be run as A) "searchterm*" or B) run multiple times, results without * might be prioritised higher then with *.
