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