Perhaps you should try some spelling variations:
linker's criteria » funder's criteria, concerns criteria
well's criterion » weyl's criterion, kelly's criterion, kelly criterion
cancer materials » carrier materials, chapter materials, laser materials
after arterial » after atrial, after anterior, after partial

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