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