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