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