Perhaps you should try some spelling variations:
swath » swat, spath
spat » spot, spam, spa
span » spin
spotters » potters, spotter, spouters
spame » spamer, space, spam
-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: (swath OR ((spat OR span) OR (spotters OR spame)))-plate*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(swath or ((spat OR span) or (spotters or spame)))-plate*".
