search_moments
Find lecture moments that explain a topic or question
Find the moments in Bettyapp's university and school lectures that explain a topic or answer a student's question. Use it when a student asks about a topic, or is stuck on a question, and a short part of a real lecture would help. Each moment has a play_url that opens the lecture at that moment: give the student the best one or two, with the lecture title, teacher and credit line. The moments come best first. If none come back, Bettyapp has no lecture on it: do not say that it has.
