Retrieve documents from MongoDB database that have specific characteristics

Hello everyone,

Today I'm trying to navigate mongoose queries.

Imagine we have a collection like this:

[
   {letter: "A", name: "Books", action: "read"},
   {letter: "B", name: "Notebook", action: "write"},
   {letter: "C", name: "Camera", action: "take photos"},
   {letter: "D", name: "Pencil", action: "draw"}
]

I want to extract a subset containing the documents with names: "Books" and "Pencil".

The expected output should be:

[
       {letter: "A", name: "Books", action: "read"},
       {letter: "D", name: "Pencil", action: "draw"}
]

Can this be achieved using the "find()" method?

Answer №1

To filter results based on specific values, you can utilize the $in operator in MongoDB queries.

db.collection.find({
  name: {
    $in: [
      "Apples",
      "Bananas"
    ]
  }
})

See it in action on the Mongo Playground

Answer №2

A different approach to using the find method with the $or operator.

db.collection.find({
  $or: [
    {
      "name": "Books"
    },
    {
      "name": "Pencil"
    }
  ]
})
