Perhaps you should try some spelling variations:
arash » crash, brash, trash
swat » sweat, swan, seat
sat » salt, satz
spate » spater, spaten, space
spacer » spaces, spaced
xpath » path
-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: (arash OR (((swat OR sat) OR (spate OR spacer)) OR xpath))-plate*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(arash or (((swat OR sat) or (spate or spacer)) or xpath))-plate*".
