Nokia Mobile Search will make it easy for you to search the web and your local content (such as notes, messages, files, contacts, etc). Previous version of Nokia Mobile Search can only search the web from Yahoo and Windows Live, and is not very useful (since you can do this from the default web browser).
One thing that you should know is that the application doesn’t search the content of a file (unlike Spotlight on Mac OS X, or Google Desktop Search), only the file names. If you are looking for something inside a file, then this application is not for you.
