How to find search phrases from yandex and google referrers?

Question

Google

How to find out what search keys used to go to pages from Yandex and Google (Without the use of metrics and analytics)
from document.referrer - in Yandex it is somehow encrypted, from Google it only gives https://www.google.ru (although it may be is the analytics cut off after processing by the script?)

Answer 1

maybe through metrics / analytics it is possible. directly in any way, they do not give.

Answer 2

going from https -> http does not pass the referrer.
the encrypted Yandex transition can be decrypted (at least some transitions), if you move your brains, everything is simple there.
