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