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