How to get multiple document using array of MongoDb id?

Question

I have an array of ids and I want to get all document of them at once. For that I am writing but it return 0 records.

How can I search using multiple Ids ?

Answer 1

For finding records of multiple documents you have to use "$in" operator Although your query is fine, you just need to add ObjectId while finding data for Ids

db.feed.find({
  "_id" : {
    "$in" : 
      [ObjectId("55880c251df42d0466919268"), 
       ObjectId("55bf528e69b70ae79be35006")
      ]
   }
});
