title: Spring Data ElasticSearch documentation on annotations etc
body: <p>I'm new to ElasticSearch and Spring Data ElasticSearch, and trying it out for a project. I went through the <a href="http://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/" rel="nofollow">documentation</a>, but couldn't find anything on the annotations like <code>@MultiField</code>. Are these things documented somewhere else? I basically needed a getting started kind of guide and some reference documentation of all the available annotations, features etc.</p>
  
  <p>Or, maybe, after I gain some knowledge on ElasticSearch, these annotations would be self explanatory?</p>
