In order to set indexed props with the low level,
entity.setProperty("foo", "bar")
Unindexed properties
entity.setUnindexedProperty("foo", "baz")
I apologize about getting the API wrong in my last message.
to get values out of indexed properties, you cast:
Date d = (Date) entity.getProperty("somedate")
If it is an unindexed property, you have to parse string
String mydata = ((Text) entity.getProperty("someunindexedprop")).getValue()

Thanks John
I wished Goole App JDO or Low level API could have done the same thing
and wouldnt have to learn one more framework.....it may be easier but
still i have to spend some time.
By the way do you know correpsonding API(setIndexedProp()) in Datastore
low level API...
If some third party frmaework can do something then i am sure Low Level
datastore api must be capable of doing the same.
Thanks,
Ravi.

Ravi,
I think you might need a MapReduce job that calls setIndexedProperty on
all your affected entities. Here's mine for you to adapt, but if you
don't know MapReduce, you'll have to check it out.
public class QuickBulkJob extends AppEngineMapper {
private static final Logger log =
Logger.getLogger(QuickBulkJob.class.getName());
@Override
public void map(Key key, Entity e, Context context) throws IOException,
InterruptedException {
setIndexedProp(e, "deactivated");
setIndexedProp(e, "feedbackReceived");
setIndexedProp(e, "email");
getAppEngineContext(context).getMutationPool().put(e);
}
private static void setIndexedProp(Entity e, String prop) {
if (e.hasProperty(prop)) {
e.setProperty(prop, e.getProperty(prop));
}
}
}
Best of luck to you.
