For complex queries so-called wildcard-characters can be used. A *represents an arbitrary number of characters, a ? represents a single arbitrary character. The query Umlaut* returns the database entries Umlaut, umlauten,
Umlautung as search result. The query *form
returns, e.g. Befehlsform, Grundform, Lautform
The system does not distinguish between upper- and lowercase characters.
