We're working on a site that has multiple countries and I'm just wondering what's the best way to organize the indices. There's not much variation between the countries - they're all similar collections so one way would be to put all countries in one index (but there's a lot of them) and then always add a filter to the search query based on the country users are searching from.
The other option would be to create a separate index for each country. This seems cleaner, but then if there was a change to the mappings, I'd need to make this update for each country.
Any advice on this?
