Perhaps you should try some spelling variations:
"funder's criteria" » "funding criteria", "pde's criteria"
"concerns criteria" » "cancer criteria", "concept criteria", "contests criteria"
"weyl's criterion" » "well's criterion", "weil's criterion"

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: (("weyl's criterion") OR ((((("linker's criteria") OR ("funder's criteria"))) OR ("concerns criteria")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"weyl's criterion\") or (((((\"linker's criteria\") OR (\"funder's criteria\"))) or (\"concerns criteria\"))))".
• Removing quotes may allow a broader search: (( weyl's criterion ) or ((((( linker's criteria ) OR ( funder's criteria ))) or ( concerns criteria )))).
• Adding a wildcard symbol may retrieve word variants: (("weyl's criterion") or ((((("linker's criteria") OR ("funder's criteria"))) or ("concerns criteria"))))*.
