Perhaps you should try some spelling variations:
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: (((( (weyl's OR well's) criterion ) OR ( weil's criterion ))) OR ((( wiener criteria ) OR ( wiener criterion )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( (weyl's OR well's) criterion ) or ( weil's criterion ))) or ((( wiener criteria ) or ( wiener criterion ))))".
• Adding a wildcard symbol may retrieve word variants: (((( (weyl's OR well's) criterion ) or ( weil's criterion ))) or ((( wiener criteria ) or ( wiener criterion ))))*.
