Perhaps you should try some spelling variations:
swash » slash, smash
awash » wash, akash, arash
swath » swat
spath » xpath, spate, spanh, spoth, spamh
spat » span, spot, spam
-plate" » -place"
plates" » places"

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 spat)))(-plate" or -plates").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((swash or awash) or (swath or (spath OR spat)))(-plate\" or -plates\")".
• Removing quotes may allow a broader search: ((swash or awash) or (swath or (spath OR spat)))(-plate or -plates ).
• Adding a wildcard symbol may retrieve word variants: "((swash or awash) or (swath or (spath OR spat)))(-plate" or -plates")*.
