java - morphia: can I index on a referenced field? -

i'm pretty reply no, figured check.

if have record references record, this:

public class account{ @id objectid id; long balance; @reference client customer; } public class customer{ @id objectid id; string name; address address @indexed long social; }

can create index based off of referenced value? instance if wish able index accounts social, can accounts given social quickly, can that?

if u wanted u utilize compund index
