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