Use 'Contains' in better exposed filters? I have a taxonomy of Office departments that I am using to filter my contacts which are brought into drupal with Ldap to search people by department. Some contacts have more info in their dept field when brought in from Ldap. 
For example 'Credit - London' instead of just credit. Is the a way to filter by contains 'Credit'? 
There are no options on the expose filter
If you use the field as textfield, then you will have options to filters department like above.
