Let Search Current File function with multiple lines

Use case or problem

When trying to check whether one note has a few lines of text from another before cutting and pasting it over, I would like to be able to Search Current File and paste in a few lines to check if there is a match. Currently, the Search Current File only works with single lines.

Proposed solution

If Search Current File functioned with multiple lines these searches would return a match and I would know that the file contains those exact couple lines.

Current workaround (optional)

WinMerge or other diff checkers. Also VSCode allows this.

This request mentions allowing multiple lines but deals more with seeing more and less with actually allowing multiple lines of markdown text to be pasted into the Search Current File function: Larger search box in `search`
