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