Sometimes you'll receive a message from a parent where they leave their name, but don't leave the name of their daughter. With parents who don't share the same surname as their child, or duplicate surnames, it's important to be able to search on the name of the parent to check which student(s) belong to them.
In Synergetic it's possible to search using the name of a Contact.
In the search screen, there is a Contact section on the right hand side.
If you enter a surname into this field, the results will be the students who have a contact with the name you enter.
