Perhaps you should try some spelling variations:
swash » slash, swath, awash
smash » slash
sweath » sheath, sweat, sweats
swat » sweat, swan, seat
sat » salt, satz
span » spin
-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 smash) OR (sweath OR ((swat OR sat) OR span)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash or smash) or (sweath or ((swat OR sat) or span)))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash or smash) or (sweath or ((swat OR sat) or span)))-plate*.
