Perhaps you should try some spelling variations:
swash » slash, smash, awash
swath » swat, spath
spat » span, spot, spam
spater » spaner, spoter, spamer
stamer » stammer
-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 swath) OR (spat OR (spater OR stamer)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash OR swath) or (spat or (spater or stamer)))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash OR swath) or (spat or (spater or stamer)))-plate*.
