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