Perhaps you should try some spelling variations:
swash » slash, awash
swath » swat
smash » slash
spath » xpath, spate, spoth, spamh, spah
spat » spot, spam, spa
seath » death, seat, heath
sat » salt, satz
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 swath) OR smash) OR (((spath OR spat) OR seath) OR (sat OR span)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((swash or swath) or smash) or (((spath OR spat) or seath) or (sat or span)))-plate".
• Adding a wildcard symbol may retrieve word variants: (((swash or swath) or smash) or (((spath OR spat) or seath) or (sat or span)))-plate*.
