In the existing version of elastic search 5+ we used our custom static field index as a "prodid" with value product id .. that was working properly that time. When we upgraded Magento to 2.3.3 with elastic search 6.8.6 we can get only default products attribute in elastic search for filter and not our custom field which we added via FieldProvider/FieldName/Resolver/prodid.php
Is there any idea How to add our custom field in search bucket of elastic search ?
