-The query function checks against the submitted (sub-)domain and recurse automatically to the (upper) top level domain.
-In the example above you have to whitelist "ad.where.com" to free the submitted (sub-)domain.
-For all matches (max. 3 per list) the query function returns the blocklist name, the line no. and the relevant (sub-)domain/host.
+The query function checks against the submitted (sub-)domain and recurses automatically to the upper top level domain(s).
+For every domain it returns the overall count plus a distinct list of active blocklists with the first relevant result.
+In the example above you have to whitelist "www.doubleclick.net" to free the submitted domain.
