Drupal 8: How to create browse by taxonomy term dropdown


I am trying to recreate in Drupal 8 the search page that somebody created in PHP. I am looking for the way to browse bibliography catalog by the Author name (which is a taxonomy term). Visitor picks Author name from the dropdown, clicks Go and gets all citation by this author. User shouldn’t type anything, just pick Author and click Go.
I installed Search API, looked from all it’s extensions, searched forums – no avail. There are more then 200 Authors, so dropdown is the only option for me.

Thank you!

This is what I am trying to recreate with dropdown
