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