Perhaps you should try some spelling variations:
slash » flash, clash, slas
span » spin
spate » spater, space, spite
spaten » spatern, spacen, spiten, spater, spateren
spacen » spachen, spaces, spaced
-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: (slash OR (span OR (spate OR (spaten OR spacen))))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(slash or (span or (spate or (spaten OR spacen))))-plate".
• Adding a wildcard symbol may retrieve word variants: (slash or (span or (spate or (spaten OR spacen))))-plate*.
