Usage

Basic Configuration

resolver is needed to resolve domains.

server {
  # ... part of server configuration
  resolver 8.8.8.8;
  location / {
    google on;
  }
  # ...
}

Google Scholar

google_scholar depends on google, so google_scholar cannot be used independently.
Because the tld of google scholar is not the same in different region, so the domain of google scholar should be specific.
Get the tld of google scholar.

curl "scholar.google.com" -I
HTTP/1.1 302 Found
Location: http://scholar.google.co.jp/

Configuration nginx.

location / {
  google on;
  google_scholar "scholar.google.co.jp";
}

Upstreaming

upstream can help you avoid name resolving cost, and decrease the possibility of google robot detection.

upstream www.google.com {
  server 173.194.38.1:443;
  server 173.194.38.2:443;
  server 173.194.38.3:443;
  server 173.194.38.4:443;
}
