title: Query the string type Date in mongodb
body: <p>This is my query in mongodb</p>
  
  <pre><code>db.order.find ({"ublExtensions.ublExtensions.extensionContent.Metadata
                  .ModificationTime": "2012-02-04T01:58:27.861Z"});
  </code></pre>
  
  <p>It is fetching the result only for the particular time zone. The modificationTime is changing on a daily basis. I have a requirement where I need to pick the data which are updated y'day...means (sysdate -1 in sql) one day data.</p>
  
  <p>How can I achieve this in mongodb? Please note the my Date is a String Type and I have a constraint where I can't change that. Someone suggested to use the ISODate.</p>
  
  <p>Please help in resolving this issue.</p>
