Deleted a search portal and all entries remains there

I did a query search portal inside a document. Deleted the search portal and all results entries remains there wirhout the search portal box. I’m afraid to delete all since it can be synced as a portal and then delete the origin.

Can you provide a Screenshot?.. I have played with Search Portal but there’s no any problem…

I can’t. I simply deleted the search portal and all content remains there in the same place without the search portal.
