Ex Libris differentiates between "databases," which have no full-text content, and "electronic collections," which include electronic portfolios and full-text. The out of the box "database search" from the Primo VE header doesn't work well because of this distinction, and the Discovery Working has recommended deactivating this search and adding a link to your external A-Z database list instead, under Configure Views, Edit View, Links Menu tab.
If you would like to activate database type collections for acquisitions purposes, you may do that. It's recommended that you suppress that top-level bib record so that it doesn't appear in your Primo search, but if you would like them to show in Primo, just make sure that the collection level link is correct and uses your proxy. You could also suppress the database level bib and use Resource Recommender to call attention to databases by title.

SLS FAQs:
The CZ Updates Task List let's you know when changes have been made to any electronic collections that you've activated. This includes changes to metadata, updates to links, removal of content from a collection, or the removal of a collection from the CZ. It's important to monitor the CZ Updates Task List to prevent your patrons from losing access to content in Primo VE. The only way you'll know if a title or collection has been deactivated is if you keep an eye on the CZ Updates Task List, or if someone complains.

The workflow described in this FAQ allows libraries to activate electronic collections with a resource type of selective package and automate the process to keep holdings up to date.
