Perhaps you should try some spelling variations:
"polynomial basis function" » "polynomial spaces function", "polynomial basis functions", "polynomial loss function"
"polynomial space fraction" » "polynomial spaces fraction", "polynomial time fraction"
"polynomial space action" » "polynomial spaces action", "polynomial time action", "polynomial space allocation"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("polynomial basis function") or ((("polynomial space fraction") OR ("polynomial space action"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("polynomial basis function") OR ((("polynomial space fraction") OR ("polynomial space action")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"polynomial basis function\") or (((\"polynomial space fraction\") OR (\"polynomial space action\"))))".
• Removing quotes may allow a broader search: (( polynomial basis function ) or ((( polynomial space fraction ) OR ( polynomial space action )))).
• Adding a wildcard symbol may retrieve word variants: (("polynomial basis function") or ((("polynomial space fraction") OR ("polynomial space action"))))*.
