Perhaps you should try some spelling variations:
swash » smash, awash
slash » flash, clash, slas
swath » swat, spath
spate » spater, spaten, spite
spateren » spaterren, spatenren, spiteren, spater
-plate" » -plates"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((swash OR slash) OR (swath OR ((spate OR space) OR spateren)))(-plate\" OR -place\")".
• Removing quotes may allow a broader search: ((swash OR slash) OR (swath OR ((spate OR space) OR spateren)))(-plate OR -place ).
• Adding a wildcard symbol may retrieve word variants: "((swash OR slash) OR (swath OR ((spate OR space) OR spateren)))(-plate" OR -place")*.
