class Paraphrase::Repository

{Repository} is were query-specific scopes are defined. They can be defined by re-opening the class inside the {Query} class definition or by using the {Query.scope scope} class method on {Query}. Both methods are equivalent.

Inside scopes defined on a {Repository}, the method has access to {Query#params} as `params`.
