-- `Equals`: performs an equality (`=`) comparison.
-- `Like`: performs a `LIKE` comparison.

+The following filters are available for ActiveRecord currently:

+- `Like`: performs a `LIKE` comparison (requires `:column`).
+- `Ilike`: performs an `ILIKE` comparison (requires `:column`).
+- `Where`: adds a generic `WHERE` clause (requires `:condition` and passes the parameter's value as

+- `Scope`: calls a method on the collection (requires `:scope` and passes the parameter's value as

 Support for more clauses as well as more ORMs will come soon.
