Perhaps you should try some spelling variations:
frendens » verendens, frenken, pendens, freudens, fremdens, freedens
frentes » frente, rentes
verbindens » verbinden, verbindend, verbindendes
frend* » freud*, fremd*, freed*

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((frendens OR frentes) OR verbindens) (frend* OR trend*).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((frendens OR frentes) or verbindens) (frend* or trend*)".
• Adding a wildcard symbol may retrieve word variants: ((frendens OR frentes) or verbindens) (frend* or trend*)*.
