Perhaps you should try some spelling variations:
"funder's criteria" » "linker's criteria", "concerns criteria", "funding criteria"
"well's criterion" » "kelly's criterion", "kelly criterion", "levy's 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 ("funder's criteria")).
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ( well's criterion ))) or ( funder's criteria )).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ("well's criterion"))) or ("funder's criteria"))*.
