Explanation:
The said query in MongoDB that retrieves documents with listing_url, name, bedrooms, and price values fields from the 'listingsAndReviews' collection, where the price falls within the range of 600 to 900.
The $gte operator and $lte operator in the find() method filters the documents where the value of the price field is greater than or equal to 600 and less than or equal to 900.
The projection operator includes the listing_url, name, bedrooms, and price fields in the result set by setting the value 1.
