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