Perhaps you should try some spelling variations:
"funder's criteria" » "concerns criteria", "funding criteria", "pde's criteria"
"linker's criteria" » "concerns criteria"
"well's criterion" » "kelly's criterion", "levy's criterion", "li's criterion"
"kelly criterion" » "energy criterion"
"weyl'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 ((("well's criterion") OR ("kelly criterion"))))) OR ((("linker's criteria") OR ("funder's criteria")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"weyl's criterion\") or (((\"well's criterion\") OR (\"kelly criterion\"))))) or (((\"linker's criteria\") or (\"funder's criteria\"))))".
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ((( well's criterion ) OR ( kelly criterion ))))) or ((( linker's criteria ) or ( funder's criteria )))).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ((("well's criterion") OR ("kelly criterion"))))) or ((("linker's criteria") or ("funder's criteria"))))*.
