• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("the patrick moore spherical astronomy series") OR ("the patrick sobere spherical astronomy series"))) OR ("the patrick moon positional astronomy series"))) OR ("the patrick core optical astronomy series")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"the patrick moore spherical astronomy series\") OR (\"the patrick sobere spherical astronomy series\"))) or (\"the patrick moon positional astronomy series\"))) or (\"the patrick core optical astronomy series\"))".
• Removing quotes may allow a broader search: (((((( the patrick moore spherical astronomy series ) OR ( the patrick sobere spherical astronomy series ))) or ( the patrick moon positional astronomy series ))) or ( the patrick core optical astronomy series )).
• Adding a wildcard symbol may retrieve word variants: (((((("the patrick moore spherical astronomy series") OR ("the patrick sobere spherical astronomy series"))) or ("the patrick moon positional astronomy series"))) or ("the patrick core optical astronomy series"))*.
