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