Perhaps you should try some spelling variations:
swash » slash, smash, awash
slas » slabs, seas, sas
swath » swat, spath
spate » spater, spaten, spite
spatenren » spaternren, spatennren, spitenren, spateren, spatere, spaterer

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 slas) OR (swath OR ((spate OR space) OR spatenren)))(-plates\" or -place\")".
• Removing quotes may allow a broader search: ((swash OR slas) OR (swath OR ((spate OR space) OR spatenren)))(-plates or -place ).
• Adding a wildcard symbol may retrieve word variants: "((swash OR slas) OR (swath OR ((spate OR space) OR spatenren)))(-plates" or -place")*.
