Why does Nautilus' search function jam directory navigation?

Question

In Ubuntu 18.04, I do this:

• Super-E to open Nautilus
• Click on Home
• Type a letter of a desired directory, e.g. d if I want to go to Documents.
• I then try to mouse-click on Documents. But at this point, Nautilus is jammed for three minutes until eventually I get a popup notification that "Search for d is ready."

My user home has only 52 directories and 22 other files.

I think that the entire subtree of my user-home is being searched for that letter d. How do I avoid that? I do wish I could use that d keypress to go to the right part of the directory listing.
