Perhaps you should try some spelling variations:
swash » slash, swath, smash
spat » span, spot, spa
spate » spane, spote, spae, spaten, spite, spare
spater » spaner, spoter, spaer, spatenr, spiter, sparer
spam » 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 (spat OR (((spate OR spater) OR space) OR spam)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(swash or (spat or (((spate OR spater) or space) or spam)))-plate".
• Adding a wildcard symbol may retrieve word variants: (swash or (spat or (((spate OR spater) or space) or spam)))-plate*.
