Specifically, in 7.7, in the options to display facets within the Administration Explorer: Dashboards: Narrow Your Search & Related Searches, allow the opportunity to display the checkboxes for the Collection Codes and/or Mat Type for an improved patron experience.
Many of our patrons prefer the PowerPAC experience (over Vega Discover Premium), and they would like to search within our specific collections. When they use the "More Search Options" feature, the viewable area per section is only four items, and scrolling is challenging. Depending on the screen size and text/accessibility settings, one facet could use a significant portion of the screen, reducing the accessibility to reach the lower lists and to reach the search button.

Vega offers a search option for the Collections facet, which would also be helpful (search book club kits for all the book club kits).
