Succeeded with Martin's help in rewriting the search query on the search.php page to avoid the errors generated by the id($var) call. Now successfully gets number of hits of search string in each article in collection. Yet to do: return list of timestamps corresponding to hits - requires editing another piece of code that uses the id($var) construction

Applied that knowledge to similar problem in player.php page, so that now successfully gets list of videos in collection and plays video file. Yet to do: get the transcript to appear. No error message appears, but I suspect it is another instance of the id($var) construction.
