title: Get cloudant (couchDB) database documents by passing a list of keys
body: <p>So I have searched a lot but I don't currently have a solution for this. Following is the query to get documents from cloudant (couchDB) database based on multiple keys ("key-1" and "key-2"). </p>
  
  <pre><code>db.getViewRequestBuilder("example", "foo").newRequest(Key.Type
                          .STRING,
                  Object.class).includeDocs(false).keys("key-1", "key-2").build()
                  .getResponse().getDocs();
  </code></pre>
  
  <p>This doesn't seem to work if I just pass a list of keys. I have a <code>List 
  &lt;String&gt; keys</code> that I would like to pass here and get all the docs. Does anyone know the simplest way to do this? </p>
