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