title: Storm-crawler crawl and indexing
body: <p>I've worked with Nutch 1x for crawling websites and using Elasticsearch to index the data. I've come across Storm-crawler recently and like it, especially the streaming nature of it. </p>
  
  <p>Do I have to init and create the mappings for my ES server that Storm-crawler is sending the data to?</p>
  
  <p>With Nutch, as long as I had the ES index up and running, the mapping took care of itself... except for some fine tuning. Is it the same for Stormcrawler? Or do I have to init the index and mapping before? </p>
