Perhaps you should try some spelling variations:
swash » awash
slash » flash, clash, slas
swath » swat, spath
sweath » sheath, sweats, sleath, sweeth, swepth
sweat » sweet, swept
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 slash) OR smash) OR ((swath OR sweath) OR (sweat OR span)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((swash OR slash) or smash) or ((swath or sweath) or (sweat or span)))-plate".
• Adding a wildcard symbol may retrieve word variants: (((swash OR slash) or smash) or ((swath or sweath) or (sweat or span)))-plate*.
