Help Search in contacts, music, pictures, etc

[Girl.Anachronism]

I cannot figure out how to search in certain applications that come preloaded on the Samsung Moment, such as contacts, and media files (photos, music, etc.), In my Music section I can quick scroll through letter, but I'd like to be able to type in a search field for a certain song or album or artist or file name, etc. I found in the menu or long press how to search the web and other apps, etc., and find a pre selected song, but no way to search for a filename that is not selected or even on screen. I would even go so far as to say a couple letters typed of a filename should be sufficient to find related files. If anyone knows how to search these - contacts, music, photos, etc., - help would be greatly appreciated. Thanks.
