Perhaps you should try some spelling variations:
slash » flash, clash, slabsh, seash, sash
slas » slabs, seas, sas
sath » sathe, saith, sathi, salth, satzh
sat » salt, satz
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: "((slash OR slas) OR ((sath OR sat) OR (spate OR spater)))(-plate" or -place").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((slash OR slas) or ((sath or sat) or (spate or spater)))(-plate\" or -place\")".
• Removing quotes may allow a broader search: ((slash OR slas) or ((sath or sat) or (spate or spater)))(-plate or -place ).
• Adding a wildcard symbol may retrieve word variants: "((slash OR slas) or ((sath or sat) or (spate or spater)))(-plate" or -place")*.
