The `ts_rank_cd` function is used as an alternative to `ts_rank` for
penalizing query words that are further apart from each other.

I'm thinking that adding a `cover_density` parameter to `SearchRank`
should be enough. If this parameter is set to `True` the function will be
switched to `ts_rank_cd`.

Comment (by Claude Paroz):

Almost a duplicate of #28194. However, #28194 also suggests adding the
`normalization` keyword parameter. Should we keep both tickets and address
both issues separately?

I guess we could close this one as duplicate of #28194 and have
https://github.com/django/django/pull/12597 address both.

Is it something you're interested in doing Hannes?

I don’t know how I missed that ticket. Sorry about that!

Sure, let’s close this ticket in favor of #28194. I’ll update my PR to add
support for the ` normalization` parameter.
