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