I see many computers that have turned off the Search toolbar in Windows 10 and this is a feature that should be turned on.
Right click on the toolbar and go to Search – Show search box

You can then search everything on your computer just by entering the term or narrow it down by going documents:apple – it will then search all your documents for the word apple.
You can do this as well with say photos: – videos: etc
You can also open up programs by keying in the program such as Word.
