Search filtering
Search filtering is a feature offered by some search engines that helps to limit the number of inappropriate search results displayed to users.
Ordinarily, Internet search engine results may include thumbnail images associated with sites matching the search criteria. If those thumbnails are associated with blocked sites, your web protection software prevents users from accessing the full site, but does not prevent the search engine from displaying the image.
When you enable search filtering, search engine feature stops thumbnail images associated with blocked sites from being displayed in search results.
Forcepoint Security Labs maintains a database of search engines with search filtering capabilities. When a search engine is added to or removed from the database, an alert is generated (see Alerting).
Search filtering is activated via the page in the Security Manager. See Configuring filtering settings, for more information.
