How to extend the SimpleSearch functionality ?It is required to filter the search result. I am able to extend the the advance Search Widget and able to hit my customAdvanceSearchController. But not able to do this in case of Simple Search widget. While going through the backoffice-widgets.xml, I can see the configuration and connection for advance search widget but I didn't get any configuration or connection for simple search. Please provide your inputs how to extend or replace the simple search?
