Perhaps you should try some spelling variations:
slash » flash, clash, slas
sath » sathe, saith, sathi, satzh
sat » satz
salt » sale
spate » spaten, spite, spare
spater » spatenr, spiter, sparer
-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: (slash OR ((sath OR (sat OR salt)) OR ((spate OR space) OR spater)))(-plate OR -place ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(slash or ((sath or (sat OR salt)) or ((spate or space) or spater)))(-plate or -place )".
• Adding a wildcard symbol may retrieve word variants: (slash or ((sath or (sat OR salt)) or ((spate or space) or spater)))(-plate or -place )*.
