Generally speaking, the Wayback Machine is not searchable in the fashion that Google is, there isn't a scale to put the thumb on.
(There are some tiny subsets which are rudimentarily full-text searchable; and some efforts to make domains findable. But nothing remotely like even Google 1.0 mapping URIs to organic terms.)
Which is really unfortunate because a lot of useful information is now essentially unfindable unless you know where it is. Maybe someone should start crawling and indexing the internet archive.
And no, the IA is already not an impartial archive: https://archive.org/post/1126216/kiwi-farms-removed-from-way...
Google likes to influence search results, hiding ones it doesn't like, and elevating those that the Company supports. Wayback Machine has been very reliable so far, I hope it stays that way.
