After a search Obsidian shows a list of all pleaces where the pattern match.
I Would like to get list of links to this items (Using Search copy function)
Does the Expand Embeds community plugin achieve this for you?
No, because as I know that plugin uses Obsidian copy search functionality and because it does not exists now this is a problem to implement.
This sounds like [search syntax / API] version of UI based Backlinks for Blocks Isn’t it?
