One of the new apps Samsung announced alongside the Galaxy Note 3 is S-Finder. The simplest way to describe it is a search app, with a big focus on local search within the device. Part of the new Air Command menu, S-Finder will find key words indexed across all of your content on the phone. Emails, files, the new Scrapbook app and a whole lot more besides can be pulled in, and search terms can be dictated by time, location and key words, too.
There is also the option to use a selection of web search engines from within S-Finder, but the focus is primarily on content you already have. We spent a little time looking specifically at S-Finder here at IFA 2013 in Berlin, so check out a quick hands on video up top.
