Perhaps you should try some spelling variations:
slas » slabs, seas, sas
sath » sathe, saith, path
sathi » sathei, saithi, pathi, sethi, fathi, kathi
sache » cache
spate » spaten, space, spite
spater » spatenr, spacer, spiter
-plate" » -plates"

Try widening your search to All Fields.

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: "(slas OR ((((sath OR sathi) OR sache) OR satz) OR (spate OR spater)))(-plate" or -place").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(slas or ((((sath OR sathi) or sache) or satz) or (spate or spater)))(-plate\" or -place\")".
• Removing quotes may allow a broader search: (slas or ((((sath OR sathi) or sache) or satz) or (spate or spater)))(-plate or -place ).
• Adding a wildcard symbol may retrieve word variants: "(slas or ((((sath OR sathi) or sache) or satz) or (spate or spater)))(-plate" or -place")*.
