        Solrb gem requires you to set the URL of your Solr instance
        either through SOLR_URL environmental variable or explicitly inside the configure block:

        Solr.configure do |config|
          config.url = "http://localhost:8983/solr/core"
        end

        If you are using Solr cloud you can specify the zookeeper ensemble urls inside the configure block
        and solrb will automatically get the solr urls from ZK:

        Solr.configure do |config|
          config.zookeeper_url = ["localhost:2181","localhost:2182","localhost:2183"]
        end

        For more information please check the solrb README file.
