# After Search Navigation

The ASN module may be used to allow customers to further adjust the results of a search or navigation request to correspond to their needs, by selecting corresponding filters. The ASN module allows you to specify which filter options will be available for customers to select.

## Setting up ASN with the configuration editor

After Search Navigation can be configured in the configuration editor within the sub-menus “ASN” (for search) and “Navigation” (for navigation). In order to make these changes, the user will need the rights of an *AfterSearchNavigationManager* in the Management Interface.

Please refer to the information on groups, roles, and user management in the [Fact Finder user management](/docs/system-maintenance-and-security/factfinder-ng-user-management.md) documentation for further information.

## ASN Search parameters

The generation of the ASN menus may be controlled by the search parameters. Each of the HTML, XML, and JSON interfaces responds to a URL query with the appropriate parameters. In the Web Service interface, program objects and corresponding attributes are passed by the interface.

Whenever data is passed to FactFinder via a URL, it is important that the encoding is set correctly. If this is not the case, special symbols and accented characters will be processed incorrectly. The default URL encoding scheme for FactFinder is UTF-8.
