Asset gallery widgets have a built in faceted search function that you can configure to fit your needs.
If you are editing a published Portal, click on "Update" to push the changes to the published Portal. The update button will be available once you have made any changes to the Portal after initial publishing. For more information on publishing, see:
Facets are filters that provide your audience with an efficient way of browsing through the assets of the Portal. On this page, you can learn how to configure and structure the facets of your Portal. They are organised in facet categories.
Once the Portal is configured and published, the visitors of your Portal will be able to share specific views of the Portal. The Portal URL adapts to search results displayed after using the search bar or selecting facets. Sharing the URL after the results are displayed will enable anyone visiting the Portal through that link to see the exact results.
