  +### `strictQuery`
  +
  +In mongoose 6.x, the option `strictQuery` is `true` by default, basically meaning that it will strip all properties from a query that are not on the schema the query is executed on.
  +
  +See [mongoose 6.0 Migration guide](https://mongoosejs.com/docs/migrating_to_6.html#strictquery-is-removed-and-replaced-by-strict).
  +
  +Example:
  +
  +```ts
  +// The following will result in a empty array
  +await AnimalModel.find({ cageNumber: 10 });
  +
  +// use the following if it is required to be used this way
  +await AnimalModel.find({ cageNumber: 10 }, null, { strictQuery: false })
  +```
