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