On /collections/ page the 'order_by' parameter is ignored.

[FredericPilon]

So, I'm trying to have a sort select in my page, that is custom made.

In collections/[a collection] it does work, I have a 'order_by' parameter, that is updated when the select is changed, and updates the order of the page.

But in the general /collections/ page, even if I put that order_by parameter in the URL, the results always stay the same.

Is there a way to take the order_by parameter and force the loop to use it?
