Where can I find the Search addon?

I have upgraded from EE 2 tot 5 and cannot locate the Search addon anywhere online, even though it is still discussed in the documentation. See https://docs.expressionengine.com/latest/add-ons/search/advanced.html . I do not see it in the online ‘store’ of addons. Am I missing something? – Jaap

RESOLVED: I discovered that it is still enabled by default as it used to be. I removed the no_results page search tags, did a few searches, added them again and now it works.
