title: Elasticsearch phrase prefix results
body: <p>I have two ES queries:</p>
  
  <pre><code>{match:{text:{query: "text box", type: "phrase"}}}
  {match:{text:{query: "text bo", type: "phrase_prefix"}}}
  </code></pre>
  
  <p>The problem is that the second query returns fewer documents than the first one, although I would expect the second query to return all records from the first one plus something extra. What am I missing?</p>
  
  <p>Thanks</p>
