title: Match specific value in mongoose populate
body: <p>Following is the schema of a user collection:</p>
  
  <pre><code>const Mongoose = require('mongoose')
  
  const Schema = Mongoose.Schema
  
  const userSchema = new Schema({
      name: {
          type: String,
          required: true
      },
      email: {
          type: String,
          required: true
      },
      password: {
          type: String
      },
      supporterOf: [{
          type: Schema.Types.ObjectId,
          ref: 'individual',
          required: false
      }],
  })
  
  module.exports = Mongoose.model('user', userSchema);
  </code></pre>
  
  <p>I want to populate 'supporterOf' which is a collection of individual (ref: individual).
  The 'supporterOf' contains an array of ObjectId.
  I am having the problem of matching the specific objectId with that ObjectId array.
  Can anyone suggest me how I can match specific ObjectId with an array of ObjectIds in populate function?</p>
