How to set product in magento2 as "new" in elastic search

So I’m using ES5.6 for now, because “ECONN REFUSED” error on previous issue I asked before. When using products data from demo yarn restore, there is “Everything new” section filled with new product (I’m using default theme).

But when I using products from my magento2 data with node --harmony cli.js fullreindex, the “Everything new” section is now empty (eventhough I have set the “Set Product as New From” field from magento “add new product”). When I checked the data on elasticsearch, I can’t find “new” attribute on products field. But catalog.json has “new” attribute on products field.

So how can I add “new” field attribute on products for my magento2?
