The Vertical Name that you set in your search configuration will now be used in the section headers, navigation and no results messaging!
You can set these vertical names in Additional Vertical Settings > Name, under the verticals configuration section.
If you’ve updated the name in the search configuration, you’ll need to either rebuild your site or make a new commit in order to have the update reflected on the frontend. You can still override these using the label attribute in verticalsToConfig.
You can learn more about this in the Customizing Pages unit.
