I am using Moodle version 3.5 and Adaptable theme (version 1.7.1 (2018073000) ).
I am looking for ways to limit my search to only book's content. The current Moodle version only allows to search for courses, which cannot be scoped to book activities. I would like to limit the search to:
1. Content available across all the books on site
2. Content available within a book
Has anyone tried that and found a good way to achieve this? An extension to this feature could be to select the activities to scope search to. For instance, search only within activities across site or within a course
