Perhaps you should try some spelling variations:
"large groups" » "large group", "target groups", "age groups"
"life groups" » "line groups", "elite groups", "five groups"
"like 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: (((("life groups") OR ("life group"))) OR ((((("like groups") OR ("large groups"))) OR ("lie groups"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"life groups\") or (\"life group\"))) or (((((\"like groups\") OR (\"large groups\"))) or (\"lie groups\"))))*".
• Removing quotes may allow a broader search: (((( life groups ) or ( life group ))) or ((((( like groups ) OR ( large groups ))) or ( lie groups ))))*.
