I am not really sure what I should be doing here, but it would seem that there should be a simple solution.
Let's say that there is a video file called "Happy Johnnys Adventure". When I just enter that into the search box and press enter, I get a lot of results. Now, lets say that I wanted to make it so that I would only get results that did not contain the string "German" in their subjects (to filter out the videos that are dubbed in German). What is the best way to do this?
