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

Try widening your search to All Fields.

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