When Atomic Search is installed, it automatically indexes the courses it is installed into. After that, it updates the index for active courses every ten hours. To update the index for a course immediately:
Click on the course, then Search within the course navigation menu.
Navigate to the three-dot button at the top right of the page.
Select Reindex Course.
The course index will be updated within a few minutes. The Status will spin while it indexes and update once the course has finished indexing.
