Perhaps you should try some spelling variations:
kelly's criterion » kelly criterion, levy's criterion, euler's criterion
linker's criteria » funder's criteria, line criteria
concerns criteria » cancer criteria, contests criteria, consensus criteria
concept criteria » consent criteria, contest criteria, context criteria
weyl's » well's, weil's

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 (kelly'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: "\"((\\"((weyl's criterion) or (kelly's criterion))\\") or (((\\"linker's criteria\\") or (\\"((concerns criteria) OR (concept criteria))\\"))))\"".
• Removing quotes may allow a broader search: (( ((weyl's criterion) or (kelly's criterion)) ) or ((( linker's criteria ) or ( ((concerns criteria) OR (concept criteria)) )))).
