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