Hi @laconica-sergey,
Thanks for the PR!
I just tried to test and reproduce any, anyway it seems this is already working on the latest 2.2-develop branch.

See my screenshots below. Can you please give me some more information where/how this is not working? Thanks!

In this case I added two products:
Samsung Galaxy S8 G950F and
Samsung Galaxy% S8+ G955F

Samung%

Samsung_

Any update on my previous question @laconica-sergey?

Hi @avoelkl,

You actually reproduced the issue: the filter doesn't apply, and your search disrespects special character in the search phrase. Search for the term 'Samsung%' should show nothing in your case and search by the phrase 'Galaxy%' should show only one product with the exact match.

To make it clear, try to search by the '%' sign — you will see both products, but the only one actually should match this search.
