Perhaps you should try some spelling variations:
swash » slash, smash, awash
arash » crash, brash, trash
swath » swat, spath
spate » spater, spaten, space
-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 arash) OR (swath OR spate))(-plate" or -((plates" OR places") or places")).
• Removing quotes may allow a broader search: ((swash or arash) or (swath or spate))(-plate or -((plates or places ) or places )).
• Adding a wildcard symbol may retrieve word variants: "((swash or arash) or (swath or spate))(-plate" or -((plates" or places") or places"))*.
