This is an optional feature offered by the plugin.
If you want to test the plugin quickly, without spending time and efforts on installing Apache Solr, we provide you with a one-click temporary Apache Solr index.
This index is hosted at https://www.gotosolr.com, our Apache Solr hosting service.
It will be available for 2 hours, after which it will be destroyed.
2 hours is far enough to test the plugin, and to decide to spend time on installing your own Apache Solr server.
First step: click on “Create my instant free Solr index” button
Second step: confirm that you are not a spam robot with Google reCAPTCHA
Third step: the temporary index settings are automatically filled for you
You have now created a hosted Apache Solr index, with it’s configuration files installed. You can now proceed with the next steps, without worrying about Apache Solr installations steps.
