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