Search problem with local music video

Ok, I have about 2 thousand local video files (music video file, mixed content). I use Kodi 16

Using Confuence skin, after I added my file store on the USB hard drive into Kodi as a folder, and set the content of the folder to local only. I want to search for these file by opening the search (move the mouse to the left). Whatever I type in, search result come out “No search result”

Is there something I do wrong, why I can’t search for these file. I install Global Search, and it doing the same thing, no result.

Example:

I have like

Hotel California.mkv
My love.mkv
So long.mkv
and many other .mkv files

I want to open up the search box, type in like Hotel, and would like the result such as Hotel California pop up. Is that possible in Kodi?
