The question and concern you have is with [Cortana search] and not [Google Search].
It appeared your question is not related to Open Specifications Protocols outlined here
https://aka.ms/openspecs and [Cortana search] are using different Community Support site, hence I can't simply redirect your post with a different tag.
I changed the tag from [openspecs-windows] to [not-supported]
Create a new question or start a discussion (microsoft.com), I prefilled the form for you with Windows 10, and Topic with [Cortana & search]
Thank you for contact Microsoft Open Specification Support.
