Get count from another index like getting count from another table using itemId

I have two tables, one for item and other for likes.

Item table store item all data.
And likes table stores item_id and user_id. Now I want to also get likes count along with item data. Which are two separate indexes.

I created this two separate indexes because both are different coming from diff. tables.
Is there any way algolia-django version can handle this?
