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