Help scopes allow you to restrict the scope of a search and limit the topics which show in help contents. In the help view help the active scope only affects search results, in the help browser it also affects the table of contents and keyword index. A scope can be defined to include only specific books or topics from the table of contents. If the documentation set has been configured to allow scoping by criteria it is possible also to define scopes which satisfy specific criteria such as "platform" = "linux".
From help contents the scope is changed by clicking on the link labelled "Scope" next to the search type in area.
This opens a scope selection dialog, click "New ..." to create a new scope.
This opens a new scope dialog which allow you to select which topics to show. If the documentation set does not support scoping by criteria the dialog will be similar to the one below, in this case only the topics in the Workbench Users Guide will be shown.
