Thanks,
I think this idea is not feasible. It will make the data filled up fast and time-consuming for posting of products.
I tried to learn and transfer attributes to the database from SQL_Latin1_General_CP1_CI_AS SQL_Latin1_General_CP1_CI_AI but the result will not be the product search
And this is the second search result, if true it will have 2 products found:
