The Account 'Search By' drop down is now multi-select, allowing you to search for an account using multiple search fields.

The default is set to search by 'Account Name'.

Tapping on the drop down icon will load all the search fields you can select.

Select all the fields you would like to search by.
A tick will appear next to all the fields which the search will check.

NOTE: The search settings will be saved and remembered until manually changed.
