Chapter 6 Search Attributes: Categories

This chapter explains the attributes available for Search Categories. This chapter contains the following sections:

• Overview

• Manage Categories

• Manage Classification Rules

Overview

End users interact with the search database in two distinct ways: They can type direct queries to search the database, or they can browse through the database contents using a set of categories you design. You assign resources in a search database to categories to clarify complexity. If a large number of items are in the database, it is helpful to group related items together. Your primary concern in setting up your categories should be usability so that end users can more quickly locate specific kinds of items.

The search server uses a hierarchy of categories called a taxonomy. The term taxonomy in general describes any system of categories. In the context of a networked resource database such as the search server database, it describes any method you choose of categorizing network resources to facilitate retrieval.

Manage Categories

When you click the Browse/Search tab under Categories, you will get the Manage Categories page. This page displays the categories in the taxonomy allowing you to browse the categories. You can also use this page to search for a category.

The attributes present in the Manage Categories page are shown in two tables. The first table lists the Manage Categories Attributes and the second table lists the Edit Category Attributes.

Table 6–1 Manage Categories Attributes

Attribute	Default Value	Description
New		Opens up the New Search Category page which you can use to create a new category.
Edit		Opens up the Edit Category page for that category where you can modify attributes of a Category.
Delete		Deletes the selected Category.
Reindex		Reindexes the database. If you have just created your taxonomy, you need to index the database to make category search available to your end users. If you have changed your categories, you need to reindex the database to make it up-to-date. Save the categories tree before you reindex the database. Load the new taxonomy.
