Perhaps you should try some spelling variations:
"kelly's criterion" » "kelly criterion", "weyl's criterion", "levy's criterion"
"linker's criteria" » "funder's criteria"
"concerns criteria" » "cancer criteria", "concept criteria", "contests criteria"
"weil's criterion" » "weyl's criterion", "white's criterion", "levy's criterion"
"line criteria" » "life criteria", "lime criteria", "slice criteria"

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 ("kelly's criterion"))) OR ((((("linker's criteria") OR ("line criteria"))) OR ("concerns criteria")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"weil's criterion\") or (\"kelly's criterion\"))) or (((((\"linker's criteria\") OR (\"line criteria\"))) or (\"concerns criteria\"))))".
• Removing quotes may allow a broader search: (((( weil's criterion ) or ( kelly's criterion ))) or ((((( linker's criteria ) OR ( line criteria ))) or ( concerns criteria )))).
• Adding a wildcard symbol may retrieve word variants: (((("weil's criterion") or ("kelly's criterion"))) or ((((("linker's criteria") OR ("line criteria"))) or ("concerns criteria"))))*.
