Hello, if I have loaded some search providers within a arrayvar in the context of server {}

    server {
            listen       127.0.1.5:80;
            server_name  endpoint;

            set $hosts "http://bing.com;http://blah.com;http://www.yahoo.com";
            array_split ';' $hosts to=$array;

            charset en;

            return 307 $array[0];
    }

When I visit that server it redirects me to a random uri escaped place, well not properly firefox complains the server is not redirecting properly.

How do I access individual elements of the array, is push/pull possible or random?

Start with the nginx configuration shown in the issue, especially the array_split directive and the return directive using $array[0]. Review the module's existing documentation or examples to determine supported indexing and push/pull behavior, then document individual-element access and the expected redirect value.
