Adding Limit Options to the Index Definition

After you have created group limits, you can add limit options to the index definition.

To add limit options to the index definition

1 Open the word_index view in the Table Editor.

Horizon displays the List Horizon Word Index Definitions window.

2 Choose the index definition you created earlier.

Horizon displays the Edit Horizon Word Index Definitions window.

3 Click Page Down or resize the window as necessary to display the Filter Information group.
4 Complete these fields for each limit option you want to include in the index (click New for each option you want to add):

File

Action

Description

Enter a description of the limit you are defining.

For example, enter “Kids Books” for a limit that restricts search results to your juvenile collections.

Important: Unless you change it in Information Portal, the description you enter here will be the name of the limit that users see in Information Portal.

Prefix

Enter a three-character prefix that identifies the limit type.

SirsiDynix recommends using a dollar sign followed by two letters (for example, “$lo” for a location limit, “$co” for a collection limit, and “$la” for a language limit). Horizon will not let you save a Filter that has more than three characters in the prefix.

MARC Map

Do one of these options:

If you are adding a limit that uses data on bib records, enter the limit MARC map code for the data you want to limit by, or click Codes to choose from a list of valid codes. (For example, if you are adding a limit that lets users restrict search results by language, enter the limit MARC map that includes the language element in the 008 tag.)

Enter the appropriate map based on the group limit you plan to assign in the Group Limit ID field (explained in Group Limit ID). Use a limit MARC map that is based on bib records, not authority records. Limit MARC maps begin with the letter L.

If you are adding a limit that uses data on item or copy records, leave this field blank.

Table Name

Do one of these options:

If you are adding a limit that uses data on item records, enter “item”.
If you are adding a limit that uses data on copy records, enter “copy”.
If you are adding a limit that uses data on bib records, leave this field blank.

Table Column

Do one of these options:

If you are adding a limit that uses data on item or copy records, enter the name of the column in the item or copy table that contains the data you want to limit by.

For example, enter “collection” to limit by collection; enter “location” to limit by location.

If you are adding a limit for data on bib records, leave this field blank.

Group Limit ID

Enter the group limit code you want for the limit option, or click Codes to choose from a list of valid codes.

The group limit (which you created in the previous task) defines the specific data by which a search will be limited if the user selects the limit option.

Processor

Enter “none”.

5 Save your changes.
