This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file,
mt-config.cgi, to customize the behavior of the system.
To restrict the weblogs included in a search on your site, you can use the IncludeBlogs and ExcludeBlogs settings. IncludeBlogs lists the blogs that will be included in the search, and ExcludeBlogs lists blogs that will be excluded from the search. Do not try to use both—IncludeBlogs will override ExcludeBlogs. The default is to search all blogs. Separate blog IDs with commas.
Default value: none
