Perhaps you should try some spelling variations:
swash » slash, swath, smash
spate » space, spite, spare
spaten » spacen, spiten, sparen, spateren
spater » spacer, spiter, sparer
-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: (swash OR (spate OR (spaten OR spater)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(swash or (spate or (spaten OR spater)))-plate".
• Adding a wildcard symbol may retrieve word variants: (swash or (spate or (spaten OR spater)))-plate*.
