• 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 survey") OR ("the patrick moocs practical autonomy survey"))) OR ("the patrick moyes practical astronomy survey"))))) OR ("the patrick moocs nautical astronomy long")).
• 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 survey\") OR (\"the patrick moocs practical autonomy survey\"))) or (\"the patrick moyes practical astronomy survey\"))))) or (\"the patrick moocs nautical astronomy long\"))".
• Removing quotes may allow a broader search: (((( the patrick moocs practical astronomy sergey ) or ((((( the patrick moocs practical astronomy survey ) OR ( the patrick moocs practical autonomy survey ))) or ( the patrick moyes practical astronomy survey ))))) or ( the patrick moocs nautical astronomy long )).
• Adding a wildcard symbol may retrieve word variants: (((("the patrick moocs practical astronomy sergey") or ((((("the patrick moocs practical astronomy survey") OR ("the patrick moocs practical autonomy survey"))) or ("the patrick moyes practical astronomy survey"))))) or ("the patrick moocs nautical astronomy long"))*.
