Advanced criteria extensions enable you to create your own advanced criteria dialog box that can be used to provide custom search capabilities, allowing users to search for custom message properties. For example:
You can display a custom advanced criteria dialog box that enables users to specify search criteria for custom properties. For example, in a public folder that receives custom messages from an on-line service, there might be custom properties such as "Company" or "Industry" that are defined for each of the messages. With a custom search dialog box, you can supply criteria fields for these custom properties that enable users to perform custom searches. For instance, a user could search for all messages with an Industry property equal to "Biomedical."
