This setting associates internal tables
of documents within the application to the form used to create them. When
refreshing or rebuilding a view index that contains "Form=" as
part of the selection criteria, Domino only checks the tables associated
with the form specified in the selection criteria instead of every table
in the application. This property should be enabled in large applications
that contain many small view indexes, as it will reduce the time required
to refresh or rebuild those indexes.
