Magento2 – Enable Search Suggestion Option in Catalog Search

In Magento2 Docs, there is this article
http://docs.magento.com/m2/ee/user_guide/catalog/search-suggestions.html

There is a mention about Enable Search Suggestion.

But in Magento 2.2 Store -> Configurations -> Catalog -> Catalog -> Catalog Search there are only these options ( I've checked all scopes )

I've checked the system.xml file of search module on a clean installation and even github branches of Magento and it seems like these options exists only in docs.

                </field>
            </group>
        </section>
    </system>
</config>

Do you have these options in your Magento2 Panel Admin?
