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