title: How to add a new field to ElasticSearch?
body: <p>I am trying to add a new field to elasticsearch - called "dateAdded" which will be used to sort the data as well. Not sure how to go about it with nodejs.</p>
  
  <p>I am looking here?</p>

  <p>I only see an example for using curl, how can I do it using nodejs with this module - <a href="https://github.com/elastic/elasticsearch-js" rel="nofollow noreferrer">https://github.com/elastic/elasticsearch-js</a></p>
  
  <p>This is how I originally indexed it:</p>
  
  <pre><code>esclient.index({  
                                index: 'projects',
                                type: 'project',
                                id: projectIdStr,
                                body: {
                                  "title": proj.title,
                                  "company": proj.company,
                                  "tags": proj.tagsArray,
                                  "defaultPicId": proj.defaultPicId
                                }
                              },function(err,resp,status) {
                                  if(err) { console.log(err);} else {
  
                                  //stored
                                  }
  
                              });
  </code></pre>
