Perhaps you should try some spelling variations:
swash » slash, swath, smash
awash » wash, akash, arash
spath » xpath, spanh, spoth, spamh
spate » spater, spaten, space, spane, spote, spame
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 ((spath OR spate) OR spat))(-plate OR -plates ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash or awash) or ((spath OR spate) or spat))(-plate or -plates )".
• Adding a wildcard symbol may retrieve word variants: ((swash or awash) or ((spath OR spate) or spat))(-plate or -plates )*.
