• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((open syllabus) OR (new syllabus)) test ) OR ( week syllabus test ))) OR ( ((open syllabus) OR (new syllabus)) digest )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((open syllabus) OR (new syllabus)) test ) or ( week syllabus test ))) or ( ((open syllabus) OR (new syllabus)) digest ))".
• Adding a wildcard symbol may retrieve word variants: (((( ((open syllabus) OR (new syllabus)) test ) or ( week syllabus test ))) or ( ((open syllabus) OR (new syllabus)) digest ))*.
