The `isIn` and `isNotIn` functions expect either a list/tuple of values, or another queryset (a subquery).

### Old-style filter conditions ### Old-style filter conditions
Prior to version 2 of the ORM, filtering conditions were limited to a predefined set of operators, and complex expressions were not supported. This old syntax is still supported, so you can use it alongside or even intermixed with new-style functions and expressions. Prior to version 2 of the ORM, filtering conditions were limited to a predefined set of operators, and complex expressions were not supported. This old syntax is still available, so you can use it alongside or even intermixed with new-style functions and expressions.
The old syntax uses keyword arguments to the `filter` and `exclude` methods, that are built as `<fieldname>__<operator>=<value>` (two underscores separate the field name from the operator). In case no operator is given, `eq` is used by default.
