How Field Data is Stored
Custom field data consists of two general types – text type fields and object type fields.
Text Type Fields
Text Type fields are stored in the database as text strings.
These fields are fully searchable to any related application. For example, role level fields can be searched though the Search People feature or any application that provides access to contact data.
You can also search and replace these values in bulk by using the Field Data tab and specifying the old and new value required.
Object Type Fields
Object Type fields are stored on the server in a resource folder on the server.
These fields can consist of files of any type, such as documents or images. Document type fields are searchable, provided the File Index option is selected (this option is only available for these types of fields).
