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