Current Ctrl+F feature is limited.
The Ctrl+F find tool should show you the number of matches and show you if there are no matches. As you press next through the matches, the tool should show you which number of the total number you are looking at. You should also be able to find and replace text.
+1 to everything but just know that find and replace already exist, default shortcut: ctrl + H

There are already multiple feature requests for this, this is the oldest I found: Adding number of instances of a word or phrase found in a note to "Search file"
