Perhaps you should try some spelling variations:
swash » smash, awash
slash » flash, slas
clash » class, flash, crash
swath » spath, sweath, sath, seath
swat » sweat, sat, seat
sleath » sheath, sleeth, sneath
swept » sweet
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 (slash OR clash)) OR (((swath OR swat) OR sleath) OR (swept OR swan)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash or (slash or clash)) or (((swath OR swat) or sleath) or (swept or swan)))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash or (slash or clash)) or (((swath OR swat) or sleath) or (swept or swan)))-plate*.
