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