Where oh where did they go?

@patuwe97 is right!

It's a must to add city, country in keywords section when you think is valuable for your clip (establishing shots).
Not necessary at all for many other clips.... sometimes P5 curators ask to put location even for "studio shots"

And why in the edit form is a text box for "Location Country" and "Location City" if it's not searchable?

And why curators recommend to fill this both text boxes although they are not searchable?

Maybe @SlimmPickens will give us an example because I think location country and location city is searchable.
But, anyway city and country are the most important keywords when you have an establishing shots, so put it also in keywords / description and title.

If you put the city name in the proper, asked for, location the search engine apparently doesn't use it according to Jonathan. It's not really what I think it's what happens.

Yup, confirming again that the location field is not searchable. The places you want words people might use when searching for your items are currently: title, description, and keywords.

But I've spoken with the team, and we're hopefully going to just remove the "location" field all together, and probably have it automatically move location field data into the keywords. Or maybe keep the field and still have it auto-move the info. I'll be sure to let everyone know when that task has been completed. :)
