The program works by preventing the user from accessing sites with certain keywords which Scientology has identified as being objectionable material for viewing by their members. This use of keywords functions as a way to prevent members from learning of guarded Scientology doctrine, such as Xenu, OT III, and other material relating to Space opera in Scientology scripture.

The Operation Clambake Web site comes up first in the search results, but when Wheat attempts to view the site, a message appears on her computer stating: "The page you have requested has been identified
