title: Querying selected fields in an entity in objectify - appengine
body: <p>I am using appengine and objectify as a backend for my app. And when i query in the datastore i get a Entity object which has the data of required row. But, using objectify how will i query entities and get oly selected fileds from it? because querying the whole entity will be heavy and it needs more data bandwidth.</p>
  
  <p>Eg : In a entity with 4 columns,  -->  Id,name,description,age.    I should query oly Id,name,age. I dont want description to be queried.</p>
