I have been playing around with the latest topics URL and found out that you can do something like

`/latest?ascending=false&order=activity&solved=no&status=open&before=3`

The semantics of before=N puzzles me though. With different N I get different results, but N does not seem to mean days and also not a date in any format I can think of.

I tried things like

`/latest?ascending=false&order=activity&solved=no&status=open&before=2018-03-15`

and

`/latest?ascending=false&order=activity&solved=no&status=open&before=100`

but I don’t get the logic.

Can somebody explain how this works?

`before` means `topics.created_at < ?` which is PARAM.to\_i.days.ago

You also have `bumped_before` which looks at bumped\_at date.

Great, thanks! Is there generally an overview/documentation of such parameters?

Mostly in the source code, this is very very ninja, our recommendation is just to rely on search here.
