Keys with the same name

[kishlaya]

Apparently, I can construct a document in MongoDB like,

{
    "title" : "mytitle",
    "somekey" : {
            "someotherkey" : "somedatahere"
    },
    "somekey" : {
            "someotherkey" : "someotherdatahere"
    }
}

Now, when I query this document in Julia, using for doc in find(collection, query()) println(doc) end it returns me -

BSONObject({ "_id" : { "$oid" : "5b2c99fe3d6c3f8629771362" }, "title" : "mytitle", "somekey" : { "someotherkey" : "somedatahere" }, "somekey" : { "someotherkey" : "someotherdatahere" } })

But if ask for doc["somekey"] then it only returns me contents of first somekey.

I agree, that having keys with same name is not quite appropriate but I think it should have been either:

• LibBSON had a way to access contents from both the keys directly (without iterating over the entire object and then matching the key names)
• Or otherwise, LibBSON threw an error (or some warning maybe?) about duplicate keys.
