ElasticPress Autosuggest

Warning: This plugin exposes your Elasticsearch publically. If not properly secured and used in conjunction with the Protected Content function, private content can be leaked publically.

Extend ElasticPress's search inputs to display search suggestions

Setup

You need to add an endpoint to your nginx config, that forwards requests for /es-search to your Elasticsearch host. Here is an example server block with the required location block:

server {
    listen       80;

    server_name  example.com;

    # Elasticsearch endpoint
    location /es-search {

        # only allow things to hit the _autosuggest API
        # change the `_endpoint` to be whatever you'd like to restrict usage to
        location ~* (.*)_suggest$ {
      
            # only allow POST requests
            limit_except POST {
                deny all;
            }
        
            # Perform our request
            rewrite ^/es-search(.*) $1 break;
            proxy_set_header Host $host;

            # Use the URL of the server here
            proxy_pass http://192.168.50.4:9200;
        }

        return 403;
    }

    root         /srv/www/example.com;

    include      /etc/nginx/nginx-wp-common.conf;
}
