Explanation:
The said query in MongoDB that retrieves all the documents with the listing_url, name, property_type, bed_type, amenities, and price fields from the listingsAndReviews collection that have a real bed as the bed type and a kitchen amenity.
The $match stage filters the documents where the bed_type field has a value of "Real Bed" and the amenities field contains the value "Kitchen".
The $project stage includes listing_url, name, property_type, bed_type, amenities, and price, so it sets their values to 1.
