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