This is necessary in order for the search widgets to find words *contained in a populated field. According to documentation, this functionality is available in ArcGIS Online already, but hasn't yet been integrated into Enterprise. As such, it leaves the search widgets in our apps quite limited in their usefulness. If a user is searching a map Dr. John Doe, they will most likely be searching for the name Doe, and may not even know Dr. Doe's first name. If the field is populated with John Doe, the widget will currently fail to find him. I imagine this functionality would be valuable across the board for those running enterprise apps.
