Hello,

When redirecting a task, there is users search control opens in a dialog window. 

Trying to search by an existing user's last name returns no results. This is because the default search condition is "Begins with" while last name is the second part of a user name.  In this case, user shoud click on an arrow to expand the advanced search options, choose "Contains" instead of "Begins with" and re-search by last name.  But  this scenario is not an intuitive and the arrow button is hardly noticed.  It there an option to change the default option of user search dialog to "Contains" automatically?
