Question

How do I set a 2D index in play morphia?

Example:

db.places.ensureIndex( { loc : "2d" } )

I assume you mean play 1.2.x.

You can’t do this from the @Indexed annotation yet, it seems: http://code.google.com/p/morphia/issues/detail?id=290

You can do it with this somewhat hacky [untested] code:

MorphiaPlugin.ds()
   .getMongo()
   .getDB('dbname')
   .getCollection('places')
   .ensureIndex(BasicDBObject(loc, "2d"));

But you might just want to do it from the shell, as you show. It’s a one time thing.
