Perhaps you should try some spelling variations:
"well's criterion" » "weyl's criterion", "kelly's criterion", "kelly criterion"
"weil's criterion" » "weyl's criterion", "kelly's criterion", "white's criterion"
"wiener criterion" » "wiener's criterion", "fisher criterion", "linear criterion"
"wiener criteria" » "inter criteria", "filter criteria", "cient 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: (((("well's criterion") OR ("weil's criterion"))) OR ((("wiener criteria") OR ("wiener criterion")))).
• Removing quotes may allow a broader search: (((( well's criterion ) or ( weil's criterion ))) or ((( wiener criteria ) or ( wiener criterion )))).
• Adding a wildcard symbol may retrieve word variants: (((("well's criterion") or ("weil's criterion"))) or ((("wiener criteria") or ("wiener criterion"))))*.
