Perhaps you should try some spelling variations:
linker's criteria » funder's criteria, concerns criteria, line criteria
cancer bacterial » cancer bacteria, carrier bacterial, centers bacterial
kelly criterion » energy criterion
cancer arterial » cancer materials, caliber arterial, after arterial

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 criterion\") or (((\"linker's criteria\") or (\"((cancer arterial) OR (cancer bacterial))\"))))".
• Removing quotes may allow a broader search: (( kelly criterion ) or ((( linker's criteria ) or ( ((cancer arterial) or (cancer bacterial)) )))).
