Given a list of documents like:

[
  {
    _id: 1,
    field1: "test",
    field2: "value2",
    fields: [
      "field1",
      "field2"
    ]
  },
  {
    _id: 2,
    field1: "value1",
    field2: "test",
    fields: [
      "field1",
      "field2"
    ]
  },
  {
    _id: 3,
    field1: "test",
    field2: "value2",
    fields: [
      "field2"
    ]
  },
  {
    _id: 4,
    field1: "value1",
    field2: "value2",
    fields: [
      "field1"
    ]
  },
  {
    _id: 5,
    field1: "test",
    field2: "test",
    fields: []
  }
]

I want to retrieve all documents that have any of the specified fields in the array, with a value “test”. For instance, in document with _id: 1, field2 is a value of fields array, and field2 has test as value. In contrast, document with _id: 5 has keys field1 and field2 with test value, but none of this fields is present in fields array. So, given the previous list of documents, only documents with _id: 1 and _id: 2 should be returned.
