Can create indices, for example:
> coll.ensureIndex({'x.$a':1})
> coll.getIndexes()
[
{
"v" : 1,
"name" : "_id_",
"ns" : "test.t",
"key" : {
"_id" : 1
}
},
{
"v" : 1,
"ns" : "test.t",
"key" : {
"x.$a" : 1
},
"name" : "x.$a_1"
}
]
You can also create an index that contains an empty field name, i.e.: "x..a"
As you cannot save/insert/upsert a field with that name, it seems like incorrect behavior to be able to index on it.
