I’m confused as to why the correct response, [codebyte]db.listingsAndReviews.find({ “address.street”: { $lte: “C” }})[/codebyte], would return documents containing street names starting with the letter, “C,” and containing more than one character. My reading of this code suggests that this should return only those documents containing the exact street name, “C,” along with those starting with the letters, “A,” through, “b.”
Question 2 wants us to, “find all the restaurants where the name of the street where the restaurant is located starts with the letter "C" or any alphanumeric character that comes before it.” So, why does the above code work when the street name is, “Coney Island Avenue?”
The "5 Star Village Cafe" whose street address is "Coney Island Avenue" is NOT INCLUDED in the less than or equal to "C" query. You can confirm it by running the query:
You’re right, I’m now finding that the document containing “street: Coney Island Avenue” is not included in the results, as makes sense given the code.
So, given that the module question and, ‘correct,’ answer are as follows…
Q: Query the listingsAndReviews collection again, this time to find all the restaurants where the name of the street where the restaurant is located starts with the letter "C" or any alphanumeric character that comes before it.
