Exploring the Depths of MongoDB Arrays

Below is the structure of my MongoDB data:

{
  "_id": "QEvgJKERy5xGNLv7J",
  "title": "test 2",
  "owner": "HQNGYZvrrdQRwLNvT",
  "markdown": "sdfasdfdasf adsfadsfasdf",
  "state": "Draft",
  "category": [
    "Bios & Memoirs",
    "Classics"
  ],
  "type": "Article",
  "lastupdate": "",
  "slug": "test-2",
  "date": 1504890635515,
  "views": "0",
  "rating": "0",
  "username": "gibigbig"
}

I am looking to retrieve all articles based on a specific category. For example:

db.documents.find({category: 'Comedy'});

However, this query is not working as expected. Any assistance on this matter would be highly appreciated.

Answer №1

Given that category is an array, you have the option to utilize $in:

db.documents.find({ category: { $in: ['Comedy'] }});

It may seem counterintuitive as you're searching for the value Comedy within the array, but that's how the syntax is defined. You can also execute a many-to-many search, such as:

db.documents.find({ category: { $in: ['Comedy','Tragedy'] }});

Alternatively, you can simply perform a single-value search as you have already discovered:

db.documents.find({category: 'Comedy'});

Answer №2

db.files.search({genre: 'Comedy'});
After troubleshooting, I resolved the issue and these commands are functioning properly.
