BadgeOS & Credly

Our site (http://ccc.coastal.edu/) uses the BadgeOS plugin, and we love it. However, when students upload a submission, we are unable to find the ones that do not contain ‘searchable’ text (that is, text that was added in the comment box upon submission).

The BadgeOS plugin allows us to search all of the submissions, but not by author name. I have made a video here that might give more detail: https://www.youtube.com/watch?v=wavcDMjA3WY&feature=youtu.be

Is there any way to search these submissions by author name, rather than the content that was typed in the text box upon submission?

Any help is greatly appreciated!
