You could precompute ranges depending on your needs.
E.g. You could have properties for each MyKind entity called things like
FOOGTZERO, FOOGTONEHUN, FOOGTTWOHUN or whatever.. hopefully, you could come
up with better names than I am.
then.. if foo > 0.. set FOOGTZERO = 1 and if foo>100 set FOOGT
So, the business requirements of my application need a query which needs to
search for a property (let's call it "foo") and a date property such that it
will filter out all objects older than a certain date. I guess in GAE/J
this would be something like
Query q = new Query("MyKind")
