Perhaps you should try some spelling variations:
kelly's criterion » kelly criterion, weyl's criterion, levy's criterion
linker's criteria » funder's criteria, concerns criteria, line criteria
contests criteria » contest criteria, context criteria, consensus 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: (( kelly's criterion ) OR ((( linker's criteria ) OR ( contests criteria )))).
• Adding a wildcard symbol may retrieve word variants: (( kelly's criterion ) or ((( linker's criteria ) or ( contests criteria ))))*.
