Can related videos avoid using username as search term?

Is there a way to remove the username from being used in finding related videos. I have 3 sites that really only have 1 user that uploads videos- the admin. However, when someone searches for a term it seams that related videos show up partly because of who uploaded the video. I would like it to pay attention to the tag words and words in the description only.
It seams to have something to do with the variable {$related_videos[$video_next].VID}

Thanks.
