# `Brix.Collection.Condition`
[🔗](https://github.com/LoamStudios/brix/blob/main/lib/brix/collection/filter_group.ex#L20)

A single filter condition within a filter group.

## Condition types

  * `:tag` — page has any of the given tags
  * `:author` — page has any of the given authors
  * `:prefix` — page slug starts with any of the given prefixes
  * `:status` — page publish status (`:published` or `:draft`)
  * `:published_after` — page published_at is on or after the given date
  * `:published_before` — page published_at is on or before the given date

The `value` field is always a list internally, even for single-value conditions.
