Perhaps you should try some spelling variations:
"linker's criteria" » "line criteria"
"funder's criteria" » "funding criteria"
"concerns criteria" » "cancer criteria", "concept criteria", "contests criteria"
"weil's criterion" » "kelly's criterion", "white's criterion", "levy's criterion"
"pde's criteria" » "ideas criteria", "peers criteria", "models criteria"
"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 ((("funder's criteria") OR ("pde'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 (((((\"linker's criteria\") or (((\"funder's criteria\") OR (\"pde's criteria\"))))) or (\"concerns criteria\"))))*".
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ( weil's criterion ))) or ((((( linker's criteria ) or ((( funder's criteria ) OR ( pde's criteria ))))) or ( concerns criteria ))))*.
