Query Mongo for multiple key value pair combinations in array field - mongodb

Question

I am trying to query for Mongo documents based on 1 many key value pairs over a large collection of documents.
I am storing the values in an array called descriptors. I cannot figure out to write the query to consistently return results.
Basically I am trying to write the following SQL query in Mongo
select * from descriptors where
(id=123 and value="Latest based on new infor")
or
(id=3221 and value="Latest new info")
I have tried the following:
db.collection.find({$or: [
{ descriptors:
{
'$elemMatch':
{
id: 123,
value: 'Latest based on new infor',
}
}
},
{ descriptors:
{
'$elemMatch':
{
id: 3221,
value: 'Latest new info',
}
}
}
]
}
Here are sample documents.
{
"_id" : ObjectId("569d62673b020a47f0401325"),
"descriptors" : [
{
"id" : 123,
"name" : "Version",
"value" : "Latest based on new infor",
"parent" : null
},
{
"id" : 345,
"name" : "Eligibility Criteria",
"value" : "Really qualified ",
"parent" : null
}
],
}
{
"_id" : ObjectId("569dac2e4e6247c01bbac47f"),
"descriptors" : [
{
"id" : 3221,
"name" : "Version",
"value" : "Latest new info",
"parent" : null
},
{
"id" : 345,
"name" : "Eligibility Criteria",
"value" : "Different Value",
"parent" : null
}
],
}
{
"_id" : ObjectId("56bce4df7aae8369d8fc705d"),
"descriptors" : [
{
"id" : 3221,
"name" : "Version",
"value" : "Latest based on new infor",
"parent" : null
},
{
"id" : 345.0,
"name" : "Eligibility Criteria",
"value" : "Really qualified",
"parent" : null
}
],
}
Any help would be appreciated,
