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.
