Perhaps you should try some spelling variations:
"crime groups" » "lie groups", "free groups", "some groups"
"like groups" » "lie groups", "large groups"
"link groups" » "sink groups", "risk groups", "disk groups"
"life group" » "lie group", "line group", "little group"

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