Searching within many subfolders freezes Desktop

GNOME nautilus 3.4.2

If I do a search for jpg file for example within a folder that contains around 5000 folders and each one has about 5000 files the desktop and anything related to Nautilus first starts to take longer to respond. After 10 to 15 minutes the whole system freezes until the search is done. In this case the search took 45 minutes which means that I could not interact with anything at least for 30 minutes.

The way I was thinking is that the search should not affect the performance on the Desktop or other Nautilus windows.

On ubuntu 18.04 LTS, the system freezes when you write something on nautilus.
The search is being made on the main thread, which breaks any possible interaction with nautilus.

Users used to the old way of searching a file inside the current folder, will get their system blocked many times because of this.
