[Developers] date range

So your decade query should use,

      "active_start":[{
        "value":null,
        "value<":"1940",
        "value>=":"1930"
      }],


I think you are currently using, 

      "active_start":[{
        "value":null,
        "value<=":"1939",
        "value>=":"1930"
      }],


Year is the earliest time for the specific year. For example, "1939" is less
than "Jan 1, 1939".
