Drupal 8 - Add taxonomy terms to search autocomplete

I have a Drupal 8 website with default search bar in my homepage. I have installed the Search Autocomplete extension to extend its functionality. Everything works great except it does not suggest taxonomy terms.

The default search block, does not search taxonomies, but search for the content which belongs to that taxonomy. Let me show you an example:

Here the Vancouver is a taxonomy term, and the things that listed(ZHR DEL, Gas Town, etc.) are content which belongs to this term. If you type the same thing in autocomplete, it does not suggest above content nor taxonomy term.

What I want is to suggest the taxonomy in autocomplete, and show the taxonomy term in the search result. Can you give me an idea to add taxonomy terms to its suggestions? Any help is truly appreciated.
