Perhaps you should try some spelling variations:
swash » slash, smash
awash » wash, akash, arash
swath » swat, spath
spate » spaten, space, spite, spante
spater » spatenr, spacer, spiter, spanter
spa » span
spam » spanm, span
-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 (((spate OR spater) OR spa) OR spam)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash or awash) or (swath or (((spate OR spater) or spa) or spam)))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash or awash) or (swath or (((spate OR spater) or spa) or spam)))-plate*.
