Hi I have tested ts_rank and ts_rank_cd for searching in Wikipedia. I would like to know which of them is better for searching in wikipedia. I have read something like that ts_rank_cd is better for long sentences, oposite ts_rank is better for single terms. But generally which of them is better to use ? Thanks for reply.
