• If you are trying to use Boolean operators, they must be ALL CAPS: (((("retail businesses books") OR ("local businesses books"))) OR ("gas business case"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"retail businesses books\") OR (\"local businesses books\"))) or (\"gas business case\"))*".
• Removing quotes may allow a broader search: (((( retail businesses books ) OR ( local businesses books ))) or ( gas business case ))*.
