Perhaps you should try some spelling variations:
"funder's criteria" » "funding criteria", "pde's criteria"
"concerns criteria" » "cancer criteria", "concept criteria", "contests criteria"
"weil's criterion" » "kelly's criterion", "white's criterion", "levy's criterion"
"weyl's criterion" » "well'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 ("weil'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 (\"weil's criterion\"))) or (((((\"linker's criteria\") OR (\"funder's criteria\"))) or (\"concerns criteria\"))))".
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ( weil'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 ("weil's criterion"))) or ((((("linker's criteria") OR ("funder's criteria"))) or ("concerns criteria"))))*.
