Jeff, not sure if I can take the approach you said to make a Annotation
interface, as the object i try to store in the datastore is a Map, more
specifically JSONObject, it my library binds JSON String, Number, Boolean,
List and Map directly to Entitiy and EmbeddedEntity...

No, I mean make up a field in your POJO that _is_ indexed and automatically
populate it with the value you want to index. A very crude example is
something like this:
class Person {
// ...
String name;
@Index String nameNormalized;
public void setName(String value) {
name = val
Ok I see, when you say synthetic index, do you mean create a Index kind on
a different namespace?

EmbeddedEntity fields are not indexable. This is mentioned in the javadocs:
https://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/EmbeddedEntity
This doesn't prevent you from making your own synthetic index in the
top-level Entity though.

On Sat, Ma
I have few question regarding Query'ing EmbeddedEntity with GAE datastore:
- Is EmbeddedEntity query-able? and Index-able?
- If so, then how to index such embedded entity?
- Does Query, query Filter works with EmbeddedEntity
- And that can we build queries that query Entity then filter
