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