Searchkick - Autocomplete with multiple models & fields

I am struggling to implement the autocomplete functionality for multiple models associated to my Post model. The search functionality works fine and returns the expected data. My autocomplete method also works fine if I implement it the way it is done in the documentation (only for posts' title however).

I also tried this answer and this one by switching Post.index.name to Post.searchkick_index.name but the autocomplete functionality does not display.

This is the code I wrote in posts_controller.rb :

def autocomplete
    render json: Post.search(params[:query],
                             index_name: [
                               Post.searchkick_index.name,
                               Tag.searchkick_index.name,
                               User.searchkick_index.name
                              ],
                             limit: 10,
                             load: false,
                             misspellings: { below: 5 })
end

I also tried:

def autocomplete
  render json: Searchkick.search(params[:query],
                                 models: [Post, Tag, User],
                                 limit: 10,
                                 load: false,
                                 misspellings: { below: 5 })
end

I get no errors with the above code, but the autocomplete functionality does not work either.

In post.rb :

class Post < ApplicationRecord
  belongs_to :user
  has_many :comments, dependent: :destroy
  has_many :posts_tags, dependent: :destroy
  has_many :tags, through: :posts_tags

  searchkick word_start: %i[title]

  def search_data
    {
      title: title,
      description: description,
      user: user.full_name
    }.merge(
      tag: tags.map(&:title),
      comments: comments.map(&:description)
    )
  end
end

As suggested in the answer section, I also tried the following:

def autocomplete
  posts = Post.search(params[:query], execute: false)
  tags = Tag.search(params[:query], execute: false)
  users = User.search(params[:query], execute: false)

  render json: Searchkick.multi_search([posts, tags, users])
end

This returns the following error: fatal - exception reentered .

I want to be able to autocomplete Post's title , Tag's title & User's full_name . How should I change my code?

Thank you in advance!

From multi_search of searchkick:

posts = Post.search(params[:query], execute: false)
tags = Tag.search(params[:query], execute: false)
users = User.search(params[:query], execute: false)

Searchkick.multi_search([posts, tags, users])
