[Zope] Z Search Interface

I am new to Zope and I am using version 2.13 from the Linux Mint 18 repository. I am trying to following the Zope2 Book, Section 18, Searching and Categorizing Content which refers to adding a Z Search Interface object to a ZCatalog. However, the Z Search Interface does not appear as an option in the Add List. I was wondering whether this object has been deprecated, and if so, whether there is any documentation on its replacement. Many thanks.
