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