• If you are trying to use Boolean operators, they must be ALL CAPS: (("energy companies") OR ((("livery companies") OR ("several companies")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"energy companies\") or (((\"livery companies\") OR (\"several companies\"))))".
• Removing quotes may allow a broader search: (( energy companies ) or ((( livery companies ) OR ( several companies )))).
• Adding a wildcard symbol may retrieve word variants: (("energy companies") or ((("livery companies") OR ("several companies"))))*.
