Perhaps you should try some spelling variations:
"kelly's criterion" » "kelly criterion", "levy's criterion", "euler's criterion"
"weil's criterion" » "white's criterion", "levy's criterion", "li's criterion"
"cient criteria" » "diet criteria", "consent criteria", "current criteria"
"floor criteria" » "flow criteria", "four criteria", "filter criteria"
"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 ("kelly's criterion"))))) OR ((("cient criteria") OR ("floor criteria")))).
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ((( weil's criterion ) or ( kelly's criterion ))))) or ((( cient criteria ) or ( floor criteria )))).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ((("weil's criterion") or ("kelly's criterion"))))) or ((("cient criteria") or ("floor criteria"))))*.
