The only useful thing about varchar is that it imposes a length constraint on a database field. Values used for indexing have a length limit, so if you change an indexed column to text somebody could try to insert values that will cause errors because the limit has been exceeded. Also you application code cannot rely on a certain size limit any more. If you are ok with that, go ahead and use text.
