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