• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((a book) OR (_ book)) reviews book ) OR ( a ((boon review) OR (book reviews)) notes ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((a book) or (_ book)) reviews book ) or ( a ((boon review) OR (book reviews)) notes ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((a book) or (_ book)) reviews book ) or ( a ((boon review) OR (book reviews)) notes ))*.
