For example, in the entity 'Movie' the property 'actors' and the property 'tags' have multiple values but the property 'date released' does not. A typical query would ask for all movies with actor= ordered by date _ released or all movies with tag=Comedy date_released. How should you avoid a combinatorial explosion in the number of indexes? A) Set the following in your entity options: exclude_from_indexes = 'actors, tags' B) Set the following in your entity options: exclude_from_indexes = 'date_published' C) Option A D) Option B.
