Perhaps you should try some spelling variations:
"open syllabus digest" » "open syllabus list", "open syllable digest", "new syllabus digest", "week syllabus digest"
"open syllabus e" » "open syllable e", "new syllabus e", "week syllabus e", "open syllabus _", "open syllabus 2", "open syllabus a"
"core syllabus heat" » "course syllabus heat", "more syllables heat", "sive syllabus heat", "core syllabus next", "core syllabus a", "core syllabus der"
"core syllabus test" » "course syllabus test", "more syllables test", "sive syllabus test", "core syllabus list", "core syllabus next", "core syllabus post"

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

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