hello,
Search will work and in Free version
You set search module for search for Books,
So for it work yours media must have Book Type and be published.
Also your media must be published.
For now When I go to Media Library software site menu item - I not see any media !!
Please check in media Library software - all media must be publish and must be in publish categories !!!
But in Media Library software Pro version, search through media also will work
Thanks,
