Enabling search filtering
By default, when a user performs a search, the results are not filtered based on the language and personalization specified. The only restriction is the accessibility of the content to the user's usergroup (if you are using ISHSTS). You may opt to enable filtered results to provide a more customized experience for the publication readers. However, enabling this option increases the time it takes to return results to the user, as each individual result has to be checked to see if it applies when the filtering conditions are taken into account.
