Perhaps you should try some spelling variations:
"elite groups" » "line groups", "finite groups", "little groups"
"life groups" » "life group", "line groups", "five groups"
"live groups" » "five groups", "line groups", "wave groups"
"like groups" » "large groups", "crime groups"
"lie 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 ("live groups"))) OR ((("life groups") OR ("elite groups"))))) OR ("like groups")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"lie groups\") OR (\"live groups\"))) or (((\"life groups\") or (\"elite groups\"))))) or (\"like groups\"))".
• Removing quotes may allow a broader search: (((((( lie groups ) OR ( live groups ))) or ((( life groups ) or ( elite groups ))))) or ( like groups )).
• Adding a wildcard symbol may retrieve word variants: (((((("lie groups") OR ("live groups"))) or ((("life groups") or ("elite groups"))))) or ("like groups"))*.
