Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.77.0. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

See Multiline Search:

VS Code now supports multiline search! Same as in the editor, a regex search executes in multiline mode only if it contains a \n literal.

So, try 1[\s\n]1 to get your desired result. \s alone is not enough to signal a multiline find or search, you must include a literal \n to signal multiline find/search.

Thanks for your reply. I understood, But it was strange when I saw the tip was Use Regular Expression

Either way, Thanks for your work, please feel free to close this issue, I had the answer I wanted. It's not a big problem.: ) Thanks for your reply again.
