The top-level description filter was added in issue #7570. Right now in AtoM there is a discrepancy between the search and browse pages - ultimately they should be one template used in different ways, but instead we are maintaining two nearly identical pages, one for browse and one for search. This is described in issue #6015. It appears that clicking the treeview's "Browse all descriptions" options will take a user to a browse page (rather than a search page), where the new top-level filter is engaged by default, rather than a search page, where it is not engaged by default. This fix will add a parameter to the query to turn the top-level filter off.
