title: App Engine Datastore Indexes: Entry Count blank?
body: <p>In the Google App Engine Admin Console, under Datastore Indexes, all of my indexes are listed as Serving. However, a lot of them are blank in the Index Entry Count and Index Storage columns. And yet still, those same indexes have a specified size on the Datastore Statistics page. What does all this mean?</p>
  
  <p>Thanks.</p>
