Hi @calmsmile ,
Thank you for writing.
I have also seen this issue on my own websites and I did some research on it. It has nothing to do with Search Analytics.
It looks like this is related to the website’s search schema. You can view it on the yoast website and some other threads related to this question.
Try to access this and you will see that URL on the website’s source:
view-source:https://yoast.com
Here are some other threads from the Yoast plugin:

https://wordpress.org/support/topic/search_term_string/
https://github.com/Yoast/wordpress-seo/issues/14455
I don’t see this as a problem and it is also not something related to the Search Analytics plugin.
Wishing you a great day!
Cornel
