How to set up nginx rewrite rules for Egey?

Question

Nginx

CMS for blogs "Egea" has such links
site.ru/?go=all/postname/
The documentation says so
rewrite ^(.*)$ /index.php?go=$1 last;
But it doesn't work, I suspect because it contains index.php and doesn't have it in the URL.
Tell me how to make a rule to leave site.ru/postname/ and site.ru/all/postname/
most likely I will do the first option, and it would be interesting to look at the second for an example.

It is correct to ask Birman.
However, here, I suspect, you need to add a slash:
rewrite ^/(.*)$ /index.php?go=$1 last;
