Perhaps you should try some spelling variations:
spath-plate » spate-plate, spath-place, spoth-plate, spamh-plate, spah-plate
xpath-plate » xpath-place, path-plate
spat-plates » spat-places, spot-plates, spam-plates, spa-plates
span-plates » span-places, spin-plates

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: ( (spath-plate OR xpath-plate) OR ( spat-plates OR span-plates )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( (spath-plate OR xpath-plate) or ( spat-plates or span-plates ))".
• Adding a wildcard symbol may retrieve word variants: ( (spath-plate OR xpath-plate) or ( spat-plates or span-plates ))*.
