title: ElasticSearch Lucene full text search using Java API
body: <p>I've recently started using ElasticSearch. I've managed to integrate them successfully, but I find the search API rather complex and confusing. The Java API is not too helpful either. How is it possible to search the following JSON for the fieldname <code>title</code> with Lucene syntax <code>AND</code> and <code>OR</code> using java api?</p>
  
  <pre><code>{
      "queryId": 2,
      "queryName": "beta",
          "query": {
              "lang": "en",
              "location": "pa",
              "title": "americanlegion OR concernedvets AND conversion"
        }
    }
  </code></pre>
  
  <p>I've tried <code>boolean query</code> but they don't feed my purpose. </p>
