Setting Up a Keyword Index for Horizon Information Portal

Horizon Information Portal version 3.x and earlier uses the standard Horizon indexes for browse and exact match searches, but requires new indexes for keyword searches. You build these indexes with a utility called Horizon Index Services. This utility provides many advantages over the standard keyword indexing in Horizon, including faster indexing and search response time; additional Boolean search capabilities; and, in many cases, more comprehensive indexing.

With Horizon Index Services, you actually create only one physical index. However, the end result will be multiple search types that act like multiple indexes. Unlike the Horizon indexes, which require a separate index for each search type, Horizon Index Services lets you define one index for all the keyword search types you want to use in Information Portal (such as title keyword, author keyword, subject keyword, series keyword, or general keyword).

This section explains these topics:

With Information Portal 4.0, you need only do these tasks to set up keyword indexes:

Creating the Index Definition

Adding Limit Options

The rest of the tasks relating to Horizon Index Services are no longer valid. In addition, Information Portal imports indexes “on-the-fly”, so you never need to import Horizon indexes into Information Portal.

The keyword search index for Information Portal uses MARC maps for indexing. If you want your Information Portal keyword searches to display the same information as your Horizon searches, the index definition you create in this task must use the same MARC maps that are used in the PAC flavor searched in Horizon.

This section explains how to find out which index is assigned to a Horizon search option, and how to find out which MARC map is linked to that index. Then, when you set up your index definition, you can make sure the definition uses these MARC maps.

This section helps you:

Find out the indexes assigned to each Horizon keyword search that you want to display in Information Portal.
Find out which MARC map is assigned to each keyword index.

To find out which indexes are assigned to each keyword search that you want to display in Information Portal

1 Open the search view in the Table Editor, or start the Search Option Table process.

The default location of this process is the Searching\PAC Control Menu folder on the navigation bar.

2 If a Search window displays, do one of these options:
In the Search for field, enter the name of the search option that you want to display in Information Portal. (In most cases, this should be the name of a PAC flavor.)
Enter an asterisk (*) to display all search options.
3 Double-click the keyword search option that you want.

Horizon displays the Edit Lister Search Lists window.

4 In the Indexes group, click the drop-down list to show all the indexes being used for this keyword search.

This is a sample window for a General Keyword search:

Note: If you have only a single index assigned to this search option, the Mq Index field shows the name of that index.

5 Write down the names of these indexes, then close the window without making any changes.
6 Repeat steps 3 through 5 in this table for each keyword search option that you want to display in Information Portal.

To find out which MARC map is assigned to each keyword index

1 Open the mq_index view in the Table Editor, or start the Indexes process.

The default location of this process is the Administration\View Control folder on the navigation bar.

2 Double-click the name of one of the keyword indexes you wrote down.

Horizon displays the Edit Horizon Index Definitions window. Here is a sample window:

3 Look in the marc_map field, and write down the name of the MARC map.
4 Close the window without making any changes.
5 Repeat steps 2 through 4 in this table to find the MARC map for each index that you use for keyword searches.
