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