We're in the process of updating our documentation so it can be used properly with some API magic (i.e. Automatically pull a list of the articles that match the Type, Subtype, and Item on a ticket, Automatically suggest a self-help article to a user based on the issue they submit, etc.).
For that, we need to find all of the articles that do not have a certain information in the article. An example is that we want to find any article that does not have #Type anywhere in the article so we can get it added.
