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