Perhaps you should try some spelling variations:
swash » swath, smash, awash
slash » flash, clash, slas
seat » set, seit, sea
sat » salt, satz
-plate" » -place"
plates" » places"

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 ((seat or sat) or spot))(-plate" OR -(plates" or places")).
• Removing quotes may allow a broader search: ((swash or slash) or ((seat or sat) or spot))(-plate or -(plates or places )).
• Adding a wildcard symbol may retrieve word variants: "((swash or slash) or ((seat or sat) or spot))(-plate" or -(plates" or places"))*.
