Search file not showing results

HI, I have a file, and when I search for "youtube" it doesn't show results. but when I search for "youtu" it will highlight the "youtu" in each name of the links and show all the links. if I add the b , again there will be no results. why is it?
thanks!

I don't know the reason, but the solution was to restart the process "windows explorer"

Hi, how are you searching the file?

a. with content indexing and using Windows search
b. opening the file in (e.g.) an office program and searching the text
c. in text displayed by an internet browser
d. some other way

If you would like to give someone the chance to comment further, I'd suggest you upload part of the file demonstrating this or a link to it or whatever is appropriate.

Thanks.
