Perhaps you should try some spelling variations:
"weil's criterion" » "kelly's criterion", "white's criterion", "levy's criterion"
"wiener criterion" » "wiener's criterion", "fisher criterion", "wieferich criterion"
"linear criterion" » "fisher criterion", "linear iteration"
"wiener criteria" » "inter criteria", "filter criteria", "cient criteria"
"weyl's criterion" » "well'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 ("weil's criterion"))) OR ((("wiener criteria") OR ((("wiener criterion") OR ("linear criterion")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"weyl's criterion\") or (\"weil's criterion\"))) or (((\"wiener criteria\") or (((\"wiener criterion\") OR (\"linear criterion\"))))))".
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ( weil's criterion ))) or ((( wiener criteria ) or ((( wiener criterion ) OR ( linear criterion )))))).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ("weil's criterion"))) or ((("wiener criteria") or ((("wiener criterion") OR ("linear criterion"))))))*.
