Perhaps you should try some spelling variations:
slash » flash, clash, slas
spath » spat, xpath, spate
swath » sweath, sath, seath
swat » sweat, sat, seat
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: ((slash OR smash) OR ((swath OR spath) OR (swat OR swan)))-plate*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((slash or smash) or ((swath OR spath) or (swat or swan)))-plate*".
