#### Video transcript

Now, let's take a look at using the equal and below operator to find entries with a taxonomy term that exist anywhere in our taxonomy hierarchy. What do we mean by that? What we mean is that when we define taxonomy in Context Stack, it's a tree structure, meaning that we have a parent, and we have children, and then grandchildren, and we can keep going down and having more and more grandchildren, right? So natural powers could also have children itself, and maybe we actually just want to find anywhere where natural powers exist, and it could be even further down the tree. So what we can do here with equal and below is we could say, superhero, and find me somewhere that natural powers exist. Maybe I don't know, or maybe I have a huge taxonomy with many levels and many terms, and I really just want to say, find me somewhere entries with natural powers, and I'm not going to specify this full path. So let's see a practical example. First, always check out the documentation, and here we see an example with equal and below. Next, let's go into Postman and try to run our query. So it's over here, equal and below, and make sure that when you're doing this that your query is checked. Initially, my query wasn't checked, and it just said entries, and it said invalid query. So make sure it's checked right here, and now what we're going to do is say, taxonomies.superhero, equal and below, natural powers. Notice I'm not specifying origin here. That's the whole point. So I'm going to click send, and now I'm going to get all the entries that have the term natural powers somewhere in the superhero taxonomy. That's it for this video. Thank you very much. Thank you. Thank you.

- Capture one concrete artifact (screenshot, Postman call, or code snippet) that proves the step works in your environment.
- Re-read the delivery versus management boundary for anything you changed in the entry model.
