Perhaps you should try some spelling variations:
"tobacco industry players" » "tobacco industry part", "tobacco industry prices", "tobacco industry patents"
"tobacco industry papers" » "tobacco industrial papers", "tobacco industry part"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tobacco industry players\") OR (\"tobacco industry papers\"))".
• Removing quotes may allow a broader search: (( tobacco industry players ) OR ( tobacco industry papers )).
• Adding a wildcard symbol may retrieve word variants: (("tobacco industry players") OR ("tobacco industry papers"))*.
