Activating Now Assist Multi-Content Response Genius Results in global or workspace search profiles overrides all other Genius Result configurations, so that global and workspace searches only display Genius Result answers from Now Assist Multi-Content Response Genius Results. Virtual Agent topic citations from Now Assist Multi-Content Response Genius Result answers in global or workspace search open the selected topic in the Now Assist panel so the user can continue their conversation on that topic. [Search Suggestions](https://www.servicenow.com/docs/access?context=search-suggestions-overview&version=yokohama&pubname=yokohama-platform-administration&ft:locale=en-US) : Search administrators with the ais_admin granular admin role can access all Search Suggestions tables.

Navigation tabs have been replaced with source facet buckets. All search results now open in a new browser tab, preserving your search in the existing browser tab. Facet buckets now show minimum search result counts, reflecting results removed by late binding content security. A new glide.ui.ais.show_all_facets system property enables you to display facets from all sources when no source is selected. (The default behavior is to hide facets until a source is selected.)
