Using find() to search for nested keys in MongoDB
database, javascript, mongodb, node.js
Solution
You have to use dot notation to get what you're looking for. It would look like:
db.collections.find({"headers.server":"gws"})
In your query, what you're asking for is documents where `headers` is an object that looks like `{server: "gws"}`, so that only work if you know what the entire subdocument is.
Problem
This is going to be a silly question, but if I have a Mongo object that is in this format: ``` { "url": "google.com", "statusCode": 301, "headers": { "location": "http://www.google.com/", "content-type": "text/html; charset=UTF-8", "date": "Fri, 22 Mar 2013 16:27:55 GMT", "expires": "Sun, 21 Apr 2013 16:27:55 GMT", "cache-control": "public, max-age=2592000", "server": "gws", "content-length": "219", "x-xss-protection": "1; mode=block", "x-frame-options": "SAMEORIGIN" } } ``` Using `db.collections.find()`, how do I find the `server` key, or any key that is nested within another key? I have tried `db.collections.find({headers:{server:"gws"}})` I have tried quoting them in all possible combinations, but the output has always been blank, or `...` Any suggestions would be appreciated.
