Win10 search function can not be used how to do

The Windows system implements various search functions through a set of indexing mechanisms, and opening some system settings by searching sometimes saves operation time. However, when this system also fails, you can't search for anything when you type in the taskbar search box or set the application search box.

If you encounter a similar problem, you can refer to the following method.
Open the run by Win+R, enter the following path to enter:
%LocalAppData%Packageswindows.immersivecontrolpanel_cw5n1h2txyewyLocalState

In the open folder, right click on the Indexed directory ——properties, click “Advanced”.

As shown in the figure below, uncheck "Also in addition to the file attributes, also allow indexing the contents of the files in this folder", and then re-tick. After waiting for the system to re-establish the index, you can search the system settings normally. It takes some time to build an index.
