Abstract
Discusses issues underlying indexing for records management. Examines: how terms that will be used to retrieve a document are selected; how many index terms should be used to ensure retrieval, the unit of information to be indexed; whether or not the system shoul be able to retrieve tha page that contains the information requested or whether it is sufficient to be able to retrieve the document that includes that page; and how to deal with long documents
