A while back, a way to generate rss syndication data from the search FtsContentProvider was created. This means to use the syndication service search has to be installed with a valid search driver (such as tsearch2-driver.)
Gustaf suggested these be decoupled in an email. This makes sense. I think we should evaluate moving to the new callback API that was developed for search 5.3 instead of service contracts at the same time.
The callback interface is mostly the same as the service contract interface, but much simpler to implement.
One of the benefits of the search style syndication compared to the rss-support package is the ability to generate RSS feeds based on any database query that returns a list of object ids instead of relying on pre created feed types.
