Perhaps you should try some spelling variations:
"spath-plate" » "xpath-plate", "spath-place", "spanh-plate", "spoth-plate", "spamh-plate"
"spath-plates" » "xpath-plates", "spath-places", "spanh-plates", "spoth-plates", "spamh-plates"
"spate-plate" » "spate-place", "spater-plate", "spaten-plate", "space-plate", "spane-plate", "spote-plate", "spame-plate"
"spat-plates" » "spat-places", "span-plates", "spot-plates", "spam-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 "spate-plate") OR ("spath-plates" OR "spat-plates")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"spath-plate\" or \"spate-plate\") or (\"spath-plates\" OR \"spat-plates\"))".
• Removing quotes may allow a broader search: (( spath-plate or spate-plate ) or ( spath-plates OR spat-plates )).
• Adding a wildcard symbol may retrieve word variants: (("spath-plate" or "spate-plate") or ("spath-plates" OR "spat-plates"))*.
