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