PyMongo - How to compare the given array exactly matches with the document

Question

I have a MongoDB document with the following attributes:

{
  "label": [
    "ibc",
    "ibd",
    "ibe"
  ],
  "location": "vochelle st"
}

and I have to return the document only if the documents label exactly matches the given array i.e., ["ibc","ibd"] and for the same, I am using the query:

db.collection.find({"location":"vochelle st","dock_label":{"$all":["ibc", "ibd"]}})

Actual Response:

{
  "label": [
    "ibc",
    "ibd",
    "ibe"
  ],
  "location": "vochelle st"
}

Expected Response:

{}

Since the label "ibe" doesn't exist in the given array, the expected result has to be the empty dictionary.

Answer 1

Give $size in your query

db.collection.find({
  location: "vochelle st",
  label: {
    $all: [
      "ibc",
      "ibd"
    ],
    $size: 2
  }
})
