Popular Photos for a Keyword

[Comfort]

I am trying to get a feed for popular photos for a particular keyword but am not having much luck.

I can do recent photos for the keyword

and I can do popular photos

Can what I am looking for be done? and if so, how?

Cheers.. and TIA

You can search a keyword and then you can click the sort by most popular button. However, it appears to me that the feed still shows the keyword images sorted by date rather than most popular. I'm not sure if this is a bug to report or a feature to request. I'll ask.
