Changing indexes in mongodb
Raw
gistfile1.txt
To change indexes in mongodb, first of all you may need to drop current index and then ensure to index on the attributes you want the index.
How to drop an index:
db.things.dropIndex("field/attributename");
How to add index of the new fields :
db.things.ensureIndex({field1:1, field2:1},{unique:true});
It need not to be a unique index but above is an example creating a composite unique index in mongodb.
