title: How to use ElasticSearch prefix query matching words of minimum size i chose
body: <p>I want to search using <strong>prefix</strong> query. I am getting results but its kind of not exactly what i want. Let me explain it in following example. Suppose i search using prefix as </p>
  
  <pre><code>"query": 
  {
     "prefix" : { "title" : "o" }
  }
  </code></pre>
  
  <p>I get results like following</p>
  
  <ol>
  <li>something <strong>of</strong> something </li>
  <li>something <strong>or</strong> something </li>
  <li>something <strong>original</strong></li>
  </ol>
  
  <p>Out of above 3 only last one is of my interest. So I wonder is there any way I can tell elasticsearch that please return only the results where prefix matched for words (or inverted indices to be more specific) which are greater than or equal to length (say) 5.</p>
