You have two Patient Docs, Patient1 and Patient2 which have embedded
Indentifier Docs. Below are the Two Docs
{
"_id": "1234",
"_rev": "123456",
"name": "Patient 1",
"gender: "MALE",
"indentifier": [
{"_id": "abc", "name": "nationalID"} ]
}
{
"_id": "5678",
"_rev": "788748",
"name": "Patient 2",
"gender": "FEMALE",
"indentifier": [
{"_id": "abc", "name": "nationalID"} ]
}
According to the CouchDB spec if the attribute is named _id you can not
have duplicates of that attribute in the DB. But in this case you where
able to save the indentifier value of the both Patient 1 and Patient 2
using the same _id value "abc". According to CouchDB this is supposed to
generate a conflict of duplication because of the _id, but it is not
happening. So what is going on here. You are basically try to make
indentifier unique across all patient documents, since there is no way
of making an attribute unique in CouchDB.

How about explaining more about your problem? This isn't enough to find
out what you mean :)
