The key to understand the answer is to enable in Everything:
Options > View > [v] Show highlighted search terms
But currently, this important feature doesn't work (or more right to say - disabled
) for items with RTL text...
I hope we will get a fix, as sooner as possible.
But I won't let you wait till then. I also can't see the highlighting, but it seems it is due to "digits" and "space".
