Perhaps you should try some spelling variations:
"elite groups" » "line groups", "little groups", "tate groups"
"life groups" » "life group", "line groups", "five groups"
"like groups" » "large groups", "crime groups"
"lie groups" » "live groups", "line groups"

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: (((("lie groups") OR ((("life groups") OR ((("elite groups") OR ("finite groups"))))))) OR ("like groups")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lie groups\") or (((\"life groups\") or (((\"elite groups\") OR (\"finite groups\"))))))) or (\"like groups\"))".
• Removing quotes may allow a broader search: (((( lie groups ) or ((( life groups ) or ((( elite groups ) OR ( finite groups ))))))) or ( like groups )).
• Adding a wildcard symbol may retrieve word variants: (((("lie groups") or ((("life groups") or ((("elite groups") OR ("finite groups"))))))) or ("like groups"))*.
