// Comma-separated list of filters to apply to results. Recognized filters are:
//
// `domain:[domain]` -- show emojis from the given domain, eg `?filter=domain:example.org` will show emojis from `example.org` only.
// Instead of giving a specific domain, you can also give either one of the key words `local` or `all` to show either local emojis only (`domain:local`) or show all emojis from all domains (`domain:all`).
// Note: `domain:*` is equivalent to `domain:all` (including local).
// If no domain filter is provided, `domain:all` will be assumed.
//
// `disabled` -- include emojis that have been disabled.
//
// `enabled` -- include emojis that are enabled.
//
// `shortcode:[shortcode]` -- show only emojis with the given shortcode, eg `?filter=shortcode:blob_cat_uwu` will show only emojis with the shortcode `blob_cat_uwu` (case sensitive).
//
// If neither `disabled` or `enabled` are provided, both disabled and enabled emojis will be shown.
//
// If no filter query string is provided, the default `domain:all` will be used, which will show all emojis from all domains.
