Explanation:
The said query in MongoDB that retrieves all the documents with the listing_url, name, address, and host fields from the listingsAndReviews collection where the host has a profile picture and has been identity verified.
Within the find() method to filter documents the query checks whether the value of the host_has_profile_pic field within the host subdocument is true and also checks whether the value of the host_identity_verified field within the host subdocument is true.
The projection stage includes the listing_url, name, address, and host fields in the output.
Improve this sample solution and post your code through Disqus.
Previous: Find Listings with superhost and at least 2 listings in the listingsAndReviews collection.
Next: Retrieve listing information with host verifications.
