Recording by keyword

Earlier this year we "upgraded" to the contour from a regular dvr box.  However I find it to be lacking in some features.  I have searched and cannot find a way to record a show by keyword (ex. figure skating, engineering).  This was possible on the regular boxes.  Please tell me there is a way to do this!   Is not always possible for me to go in and manually search for shows with the keywords I want.  Additionally it can take a long time to manually add every show.  I'm seriously considering going back to the old box, as I have found the only benefit of the contour is that it can record 6 shows at a time.  It is inferior in every other category.  However if you can direct me as to how to record by keyword then I would be happy to stick with the contour.   If it is not available please add it.  It is an important feature that is missing from contour!
