I’m interested in building a tag union capability that would mimic how tag intersections are currently implemented (Tag intersections page): essentially the same result as intersections (the default category/Latest view), but doing an OR on multiple tags rather than an AND. I would appreciate any suggestions as a new Discourse developer.
My thoughts (so far) are as follows:
Searching on multiple tags via the search page essentially provides tag-union functionality (Does multiple tag search support AND vs OR?). The problem is that I don’t want the search results view – I want the default category page. Could search results be redirected to accomplish this?
If search results can’t be redirected, I’m open to attempting a /tags/union/ route (and have been looking into how intersection works). I would prefer to do this via plugin, but I am concerned that that is not something that could currently be accomplished via a plugin. Any suggestions here would be appreciated.
If there is sufficient user interest to add a tag-union capability into the Discourse core, I’d be willing to do it and submit a PR, but I’m hoping to find an alternative. Thanks in advance.
Building queryParam arrays using the paramName syntax is a backend-framework-specific thing, and I don’t think it’s supported natively by Ember. We might be able to make it work, but I just had a quick look at the server-side implementation of the tags filter and it looks like we also support a space-separated list.
