mkdocs-material: Unable to create Search Page

I’m trying to create a search page as described here: https://stackoverflow.com/questions/63106842/how-do-i-implement-a-search-page-on-a-mkdocs-site

My expectation was that I could do this with:

theme:
  name: material
  include_search_page: true

However this throws:

WARNING -  Template skipped: 'search.html' not found in theme directories.

I’m looking to achieve the ability to search via url params similar to this example: http://readthedocs.sheets.ch/search?q=test

My yaml file is here: https://github.com/sasjs/sasjs.io/blob/master/mkdocs.yml

I checked that…

• [ x] … the documentation does not mention anything about my problem
• [ x] … the problem doesn’t occur with the default MkDocs template
• [ x] … the problem is not in any of my customizations (CSS, JS, template)
• [ x] … there are no open or closed issues that are related to my problem

Expected behavior

setting include_search_page: true would give me a SITENAME/search page that will accept url params.

Actual behavior

error in console, no search.html generated

Package versions

• Python: 3.8
• MkDocs: 1.1.2
• Material: 5.5.0

Project configuration

theme:
  name: material
  include_search_page: true
