Can I filter from the querystring?

Hello.

I think that this just works on your site (both show the same results): https://adventuretaco.com/tag/idaho,camping/
https://adventuretaco.com/tag/camping,idaho/

Maybe you should hack your theme to reflect that there are two tags taking action, because it only takes care of the first one right now.

Regards!

Thanks, but that seems to OR the tags, rather than AND them.

Your blog prevents complex queries on permalinks, but I think that should work (it doesn’t): https://adventuretaco.com/tag/4wd+camping+webster-pass

Instead, you can use the parameters version: https://adventuretaco.com/?tag=4wd+camping+webster-pass

Separating values by “,” is “OR”, and separating them by “+” is “AND”.

All this is based in the WordPress Query class, so you can play with more complex combinations of parameters: https://developer.www.ads-software.com/reference/classes/wp_query/

If this is still not enough for you, just check the REST API: https://developer.www.ads-software.com/rest-api/ You can enable custom queries and other interesting things ;).

Awesome, thanks!
