Within "location /idx/", dynamically generate the new url, and issue a
redirect to that. "dynamically" means "use one of the embedded languages,
or else talk to an external server".

An incomplete example using fastcgi and php is:

file /tmp/idx-fixup:
"""
<?php
$old = $_SERVER[REQUEST_URI];
$new = str_replace('_', '-', $old);
$new = substr_replace($new, '/property', 0, 4);

header("Status: 301 Moved Permanently");
header("Location: $new");
?>
"""

fragment of nginx.conf:
"""
        location /idx/ {
            include fastcgi.conf;
            fastcgi_pass  unix:php.sock;
            fastcgi_param  SCRIPT_FILENAME    /tmp/idx-fixup;
        }
"""

Good luck with it,
