Autocomplete by some fileds of different tables

Hi every body.
I'm new in elastic search world.
And I want to use Nest in Core 2.2.
I want to change NopCommerce search to auto suggester.
But I do not know, how to create INDEX by variant fields of different tables(for example: product name, category name,producer name fields of Products, Categories,Producers, Product attributes, Product Special Attribute tables)
for the result, I want when I typing(for example) "soft" , then suggest me all products in software category, or when I typing "snapdragon", then suggest me all Mobiles that have "snapdragon" in it's product attributes.
On the whole, how to create INDEX, how to update INDEX after Delete,Update and Insert actions.

Please advice me, if possible.
Thanks a lot.
