Perhaps you should try some spelling variations:
slabs » slab
sath » sathe, saith, sathi
pathe » paths, mathe, patho
swat » sweat, swan, sat
spate » spaten, space, spare
spater » spatenr, spacer, sparer
spite » spine
-plate » -place
plates » places

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 pathe) OR swat) OR ((spate OR spite) OR spater)))(-plate OR -plates ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(slabs or (((sath or pathe) or swat) or ((spate or spite) or spater)))(-plate OR -plates )".
• Adding a wildcard symbol may retrieve word variants: (slabs or (((sath or pathe) or swat) or ((spate or spite) or spater)))(-plate OR -plates )*.
