Perhaps you should try some spelling variations:
"open syllabus digest" » "open syllabus list", "open syllabus test", "open syllable digest", "new syllabus digest", "week syllabus digest"
"open syllabus next" » "open syllable next", "new syllabus next", "week syllabus next", "open syllabus test", "open syllabus der", "open syllabus e"
"core syllabus heat" » "course syllabus heat", "more syllables heat", "sive syllabus heat", "core syllabus test", "core syllabus a", "core syllabus der"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"open syllabus digest\") OR (\"open syllabus next\"))) OR (\"core syllabus heat\"))".
• Removing quotes may allow a broader search: (((( open syllabus digest ) OR ( open syllabus next ))) OR ( core syllabus heat )).
• Adding a wildcard symbol may retrieve word variants: (((("open syllabus digest") OR ("open syllabus next"))) OR ("core syllabus heat"))*.
