• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("the patrick moocs practical astronomy sergey") OR ("the patrick moocs practical astronomy surveys"))) OR ("the patrick mons positional astronomy sergey"))) OR ("the patrick moocs practical astronomy survey"))) OR ("the patrick nos nautical astronomy sergey")).
• 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 mons positional astronomy sergey\"))) or (\"the patrick moocs practical astronomy survey\"))) or (\"the patrick nos nautical astronomy sergey\"))".
• Removing quotes may allow a broader search: (((((((( the patrick moocs practical astronomy sergey ) OR ( the patrick moocs practical astronomy surveys ))) or ( the patrick mons positional astronomy sergey ))) or ( the patrick moocs practical astronomy survey ))) or ( the patrick nos nautical astronomy sergey )).
• Adding a wildcard symbol may retrieve word variants: (((((((("the patrick moocs practical astronomy sergey") OR ("the patrick moocs practical astronomy surveys"))) or ("the patrick mons positional astronomy sergey"))) or ("the patrick moocs practical astronomy survey"))) or ("the patrick nos nautical astronomy sergey"))*.
