# Boolean sorting

In Sitecore Content Hub, Boolean properties have three possible values:

1. *true*
2. *false*
3. *null*

When sorting results by a Boolean property, *A to Z* results are returned in the following order:

1. Assets that have the Boolean property set to *false*.
2. Assets that have the Boolean property set to *true*.
3. Assets that do not have the Boolean property set, which equals *null*.

When sorting results by a Boolean property, *Z to A* results are returned in the following order:

1. Assets that have the Boolean property set to *true*.
2. Assets that have the Boolean property set to *false*.
3. Assets that do not have the Boolean property set, which equals *null*.

By default, a Boolean property is *null* and items with this property are always last in the sorted list.
