Perhaps you should try some spelling variations:
slabs » slab
sath » saith, sathi, path
sathe » saithe, sathie, pathe, satze, sache, mathe
kathi » kathy, fathi
spate » spaten, space, spite
spater » spatenr, spacer, spiter
-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: (slabs OR ((((sath OR kathi) OR sathe) OR satz) OR (spate OR spater)))(-plate OR -place ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(slabs or ((((sath or kathi) or sathe) or satz) or (spate OR spater)))(-plate or -place )".
• Adding a wildcard symbol may retrieve word variants: (slabs or ((((sath or kathi) or sathe) or satz) or (spate OR spater)))(-plate or -place )*.
