but:
test> db.things.drop() true test> db.things.save({"array": [ 1, 2, 3 ]}) test> db.things.save({"array": [ 2, 3, 4 ]}) test> db.things.createIndex({array: 1}, {unique: true, dropDups: 1}) E11000 duplicate key error index: test.things.$array_1 dup key: { : 3.0 }
This only seems to happen if there are 2 or more duplicates in the array; with 1 duplicate, it works correctly with either true or 1 as argument to dropDups
