Perhaps you should try some spelling variations:
linker's criteria » funder's criteria, concerns criteria, line criteria
weil's criterion » weyl's criterion, kelly's criterion, white's criterion
concept criteria » contest criteria, context criteria, concerns criteria
consent criteria » contest criteria, context criteria, consistent 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: "((\"weil's criterion\") or (((\"linker's criteria\") or (\"((concept criteria) OR (consent criteria))\"))))".
• Removing quotes may allow a broader search: (( weil's criterion ) or ((( linker's criteria ) or ( ((concept criteria) or (consent criteria)) )))).
