Perhaps you should try some spelling variations:
slas » slabs, seas, sas
sath » sathe, saith, sathi
swat » sweat, swan, sat
spaten » spater
spateren » spater
-plate » -plates, -place

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: (slas OR ((sath OR swat) OR (spaten OR spateren)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(slas or ((sath or swat) or (spaten OR spateren)))-plate".
• Adding a wildcard symbol may retrieve word variants: (slas or ((sath or swat) or (spaten OR spateren)))-plate*.
