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.
The filesystem path to the search_templates directory, which is where your search templates should be located. This setting defaults to ./search_templates, which means that the search_templates directory is in the same directory as the mt.cgi file; you probably don’t need to change this setting, unless you have moved your search_templates directory.
Default value: ./search_templates/
