Perhaps you should try some spelling variations:
slas » slabs, seas, sas
sath » saith, sathi, path
sathe » saithe, sathie, pathe, satze, sache, mathe
spate » spater, space, spite
spaten » spatern, spacen, spiten, spater, spateren
-plate » -plates

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