• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"the patrick moocs practical astronomy sergey\") OR (\"the patrick moocs practical astronomy surveys\"))) or (\"the patrick moore practical astronomy sergey\"))) or (((\"the patrick moocs nautical astronomy sergey\") or (\"the patrick hoc nautical astronomy survey\"))))".
• Removing quotes may allow a broader search: (((((( the patrick moocs practical astronomy sergey ) OR ( the patrick moocs practical astronomy surveys ))) or ( the patrick moore practical astronomy sergey ))) or ((( the patrick moocs nautical astronomy sergey ) or ( the patrick hoc nautical astronomy survey )))).
• Adding a wildcard symbol may retrieve word variants: (((((("the patrick moocs practical astronomy sergey") OR ("the patrick moocs practical astronomy surveys"))) or ("the patrick moore practical astronomy sergey"))) or ((("the patrick moocs nautical astronomy sergey") or ("the patrick hoc nautical astronomy survey"))))*.
