How to compose nginx config file for google bot redirect?

Question

Nginx

There is a site on ajax. He has a static snapshot in the directory
_escaped_fragment_
. You need to write a rule to redirect the Google bot request to the static version of the site.
An example of a static address: Googlebot
/_escaped_fragment_/page/nerjav/index.html
request:

"GET /?_escaped_fragment_=/page/nerjav HTTP/1.1" 404 232 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

My code doesn't work correctly:

# nginx configuration
location / {
if ($query_string ~ "^_escaped_fragment_=$"){
rewrite ^(.*)$ /_escaped_fragment_$1/index.html? break;
}
if ($query_string ~ "^_escaped_fragment_=(.*)$"){
rewrite ^(.*)$ /_escaped_fragment_$1/%1/index.html? break;
}
}

Returns:

HTTP/1.1 404 Not Found
Server: nginx/1.4.3
Date: Thu, 24 Apr 2014 10:11:01 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive
Content-Encoding: gzip
