如何通过MongoDB中对象数组的多个条件过滤文档

Question

Suppose, I have a collection in which each document looks like following:

Is it possible to find all documents of this collection based on following multiple conditions on Objects in modules array.

{_id: OID123, status: available} and {_id: OID456, status: complete}

So that, it should return document similar to following:

{modules: [{_id: OID123, status: available}, {_id: OID456, status: complete}, {_id: OID789, ...}] }

Thank You everyone!

I managed to solve this problem by following query using $all operator:

db.collection.find({
  "modules": {
    $all: [
      {
        $elemMatch: {
          "_id": "OID1",
          "status": "available"
        }
      },
      {
        $elemMatch: {
          "_id": "OID2",
          "status": "complete"
        }
      }
    ]
  }
})
