Do the "strict" and "strictQuery" options apply to subdocuments not in schema?

[rwmia]

I have a question about strict and strictQuery, specifically how they apply to subdocuments in Mongoose 6.x

Lets say I have this schema below:

var zooAnimalSchema = new Schema({
  animal_name: {
    type: String
   },
  animal_features: {
    trunk_length: {
      type: String
    }
  }
},
{
strict: true,
strictQuery: true
});

Example 1

zooAnimalSchema.findOneAndUpdate({
        _id: animal_obj_id
      }, {
        $set: {
         animal_features: {
             trunk_length: '40',
             random_property: 'random text'
          }
        }
      })
      .exec(function (err, res) {});

Question: Will "random_property" get saved to the doc even though it is not in the schema?

Example 2

zooAnimalSchema.find({
        'animal_features.random_property' : 'random_text'
      })
      .exec(function (err, res) {});

Question: Will "animal_features.random_property" get queried even though it is not in the schema?

Can anyone with knowledge please answer? I am worried about upgrading mongoose due to the strict and strictQuery, specifically if applied to subdocuments.

@rwmia random_property: 'random text' will not get saved if strict: true.

strictQuery only affects the filter portion of the query, _id: animal_obj_id in your example.
