I want students to be able to search on course terminology throughout my course's content. For instance, to prepare for a technical review, they could look for the multiple references for "gestural" across assignments, pages, and discussions. 

Is there a way for them to search now?

I saw a 2015 response to this question here where someone had manually configured Google Search with html and javascript, but this will probably not be helpful for my colleagues who are not familiar with either of these. https://community.canvaslms.com/t5/Question-Forum/Good-way-to-search-content-within-a-course/m-p/544....
