Formulating Complex Queries Using Templates

While many users have relatively general information needs, users who are familiar with a certain topic may have more specific or complex information needs. Such users already have some knowledge of a subject and its concepts, and they need to find information on a specific aspect of a certain entit...

description While many users have relatively general information needs, users who are familiar with a certain topic may have more specific or complex information needs.
