Perhaps you should try some spelling variations:
swash » slash, smash
awash » wash, akash, arash
swath » swat, spath
sweat » sweet, swept
spate » spater, spaten, space
-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 awash) OR ((swath OR sweat) OR spate))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash OR awash) or ((swath or sweat) or spate))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash OR awash) or ((swath or sweat) or spate))-plate*.
