Hi Muhammad,
Unfortunately you cannot use the default search filters if you use a microflow. The easiest way is to use XPath or database. Otherwise you have to build this yourself. You can create an entity that stores your search filters and use this in your datasource. When you create a data grid and select a microflow, mendix asks whether you want to use server-side paging, sorting and searching, this can help you with your setup.
Hope this helps!
