# Deep linking URL format

Deep linking uses the `deeplink` URL query parameter to create external bookmarks to the Discovery Framework.

The general form of the URL is:

    http://portalhost:port/path/to/page?deeplink=JSON-ARRAY-OF-DATASOURCE-STATES

The following is a record filter example:

    http://localhost:8080/web/guest?deeplink=[{"default":
    {"queryFunctions":[{"class":"RecordFilter","recordFilter":
    "Designation:BestBuy"}]}}]
