Perhaps you should try some spelling variations:
swash » slash, swath, smash
slas » slabs, seas, sas
swat » sat, seat, stat
sleath » sheath, sleeth, sneath
sweat » sweet
swept » sweet
swan » san, span
-plate » -plates, -place

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 slas) OR ((swat OR sleath) OR ((sweat OR swept) OR swan)))-plate.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((swash or slas) or ((swat or sleath) or ((sweat OR swept) or swan)))-plate".
• Adding a wildcard symbol may retrieve word variants: ((swash or slas) or ((swat or sleath) or ((sweat OR swept) or swan)))-plate*.
