Perhaps you should try some spelling variations:
"linker's criteria" » "funder's criteria", "concerns criteria"
"levy's criterion" » "kelly's criterion", "lane's criterion", "li's criterion"
"kelly criterion" » "energy criterion"
"weyl's criterion" » "well's criterion", "weil's criterion"

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 criterion") OR ("levy's criterion"))))) OR ("linker's criteria")).
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ((( kelly criterion ) or ( levy's criterion ))))) or ( linker's criteria )).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ((("kelly criterion") or ("levy's criterion"))))) or ("linker's criteria"))*.
