Basically I have gone through my datastore persist-able classes and have 
annotated properties that I never need to query on like this:

@Extension(vendorName="datanucleus", key="gae.unindexed", value="true") 
private Long random;

I needed to test whether or not JDO removed the index when I changed the 
POJO by annotating a property as unindexed.

So I created a simple test to read in an existing entity, updated it (with 
properties holding the exact same values as before), then finally queried on 
it using the now unindexed property "random". I woud have expected for it to 
not appear again once updated (because the property is now unindexed), which 
would have suggested that JDO was handling the index deletion correctly, but 
it appears not. 

Are there any settings that I may need to change in order to allow JDO to 
delete the now un-needed single property indexes? Is there a way I can 
remove / vacuum these single property indexes (that I don't need anymore) 
myself?

Thanks,

Mark
