AJAX search on columns from another table

ecomevo

I have columns on a datatable that are from a product table and other columns from an attribute_values table. The attributes table is related to the attribute_values table via the foreign key attribute_id. The attributes table which hold the name of each unique attribute.

The attributes table is flexible, allowing a variable number of attributes to be stored from a variety of different other models using attributable_id and attributable_type fields. How do I make these fields searchable over AJAX using DT with yajra/laravel-datatables?

For instance, I might have attributable_id=1 AND attributable_type='Product' AND attribute_id=5.
