Thread: BUG #17924: Inverted behavior of "Date" and "Reverse Date" when searching a mailbox archive

The following bug has been logged on the website:

Bug reference:      17924
Logged by:          Hans Buschmann
Email address:      buschmann@nidsa.net
PostgreSQL version: Unsupported/Unknown
Operating system:   Postgres Website Mailing List search
Description:

I recently did a search on pgsql-hackers.

When changing the order of the result set from "Rank" to "Reverse Date" I
observed that "Date" gives the results from newest to oldest while "Reverse
Date" gives them from oldest to newest.

This seems to me a mismatch and quite confusing.

The semantics of Date and Reverse Date should be corrected (exchanged)

Any thoughts?

It's been like that for a decade or two, and you are the first to
complain AFAIR.  Changing it at this point would doubtless add a
lot more confusion than it subtracts.

We could perhaps change to some other terms entirely, like
"Newest First" and "Oldest First", but I'm not convinced that
that's an improvement either.

Hello Tom,


I don't mind the exact wording, but it should be semantically correct.


Order by date is ascending (as in SQL).


I would propose to change the wording, perhaps like Newest to oldest (or your suggestion) and make sure, that the selected order shows up in the results.


It is only part of the WebSite, so I don't fear any automation difficulties.
