The redirect in the custom_search_submit() function doesn't respect the "path" key in the hook_search_info() implementation.

The custom_search_submit() function redirects the search based on what the user selects in the dropdown (i.e. "Site content", "Users"). The problem is that the redirect doesn't respect the "path" key set in the search module's hook_search_info() implementation. This is a problem for contributed modules such as Faceted Navigation for Search that use a different path than their module name. In this example the expected search path is "search/content", however this module redirects to "search/search_facetapi".
