Search inside a course

Enrolled learners (and you, on your own courses) get a Search this course box on the course page. It finds where the course said something: lesson text, self-check questions and answers, and image descriptions, the alt text, captions, and credits that every figure in this catalog is required to carry.

Be precise with students about that last part: it searches the text attached to images, not the pictures themselves, which is why the empty state says so in those words.
