title: Search an enrollment device on Device Provisioning Service via initialTwin tag
body: <p>I want to search a specific enrollment device on DPS (based on its 'OL' tag). For that, I use the next piece of code:</p>
  
  <pre><code>QuerySpecification querySpecification = new QuerySpecificationBuilder("*",QuerySpecificationBuilder.FromType.ENROLLMENTS)
              .where("initialTwin.tags.OL='12345678ABCD'")
              .createSqlQuery();
  Query query = provisioningServiceClient.createIndividualEnrollmentQuery(querySpecification);
  </code></pre>
  
  <p>But, when I execute query.next() to fetch the results, always is returning all the devices in the DPS.</p>
  
  <p>I've also tried to use the deviceId in the "where" clause but it returns all devices too.</p>
  
  <p>What I'm doing wrong?</p>
