Perhaps you should try some spelling variations:
"life groups" » "lie groups", "life group", "elite groups"
"like groups" » "lie groups", "large groups", "crime groups"
"line groups" » "lie groups", "link groups", "linear groups", "online groups"
"line group" » "lie group", "linear group", "online group"

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