Simple Instructions:

To add a classifier, select it using the "Select classifier to add" pull-down list near the bottom and then click "Add Specified Classifier". A window appears entitled "Configuring Arguments"; instructions for this dialog are just the same as for plugins (see Document Plugins). Once you have configured the new classifier, it is added to the end of the "Currently Assigned Classifiers" list.

To remove a classifier, select it from the list and click "Remove Selected Classifier".

To change the arguments a classifier, select it from the list and click "Configure Selected Classifier" (or double-click on the classifier in the list).

The ordering of classifiers in the collection's navigation bar is reflected in their order here. To change it, select the classifier you want to move and click "Move To Top", "Move Up", "Move Down", or "Move To Bottom".

For further information on classifiers read Chapter 2, Greenstone Developer's Guide -- Getting the most out of your documents.

Advanced Instructions:

The CustomAZList classifier is a special classifier that builds an alphabetical selection list ("AZList") and allows you to specify the letter ranges. This classifier has its own configuration dialogue. When a metadata element is selected, the "Ranges" tree automatically becomes populated with appropriate values. Expand or collapse the tree as desired. Select any two values and click "Merge" to specify a range, or select a previously merged value and click "Split" to restore the values contained within. When satisfied with the ranges, click "OK" to begin processing the documents in the collection. You can "Cancel" the dialog without making any changes to the collection.
