I'm having URLs like:

index.php?q=123&w=456&e=789

and I need to rewrite them in something like:

index/123/456/789

without using "if".

So far I've tried:

location / {
    rewrite ^/index.php\?q=(.*)&w=(.*)&e=(.*)$ /index/$1/$2/$3;
}

But it doesn't work. Any ideas?

The short answer is you can't without using if.

The long answer is regex in the rewrite syntax only matchs the URI.

Try something like this:

    location /index.php {
        if ($args ~ "^q=(.*)&w=(.*)&e=(.*)") {
            set $arg_q $1;
            set $arg_w $2;
            set $arg_e $3;
            rewrite_log on;
        rewrite ^ /index/$arg_q/$arg_w/$arg_e last;
        }
    }
