Search API Term With Depth

This module brings Core's "Term with Depth" Views filter and argument (contextual filter) options to search_api-based views.

After the module is installed, when you add a Views filter or argument (contextual filter) for a taxonomy term field, you will see a select list of numbers and the following description:

The depth will match content tagged with terms in the hierarchy. For example, if you have the term "fruit" and a child term "apple", with a depth of 1 (or higher) then filtering for the term "fruit" will get content that are tagged with "apple" as well as "fruit". If negative, the reverse is true; searching for "apple" will also
pick up content tagged with "fruit" if depth is -1 (or lower).
