title: Combine springBoot with elasticsearch 2.x
body: <p>I try to use spring boot 1.3.3 to realise project that communicate with elasticsearch.
  After many searches in the net, I found that spring-boot-starter-data-elasticsearch is not good in my case because it's using Elasticsearch 1.5 and i have to use Elasticsearch 2.2
  There is still a hope to use spring boot ?</p>
