You create a MARC map to control what tags and subfields Horizon indexes in this new keyword search. You may already have a MARC map on your Horizon system that you can use for this new keyword index.
This section contains only an example of a MARC map setup for a title keyword index. Depending on what type of keyword index you are creating, your MARC map setup may be different. (For complete information on creating MARC maps, see MARC Maps.)
To create a MARC map for the keyword index
View: marc_map
Process: Administration\Index Control Menu\MARC Map Table
1 | In these fields, do the following: |
Field |
Action |
Marc_map Code |
Enter the code that identifies the MARC map. For example, if you are creating a Title Keyword index, you could name the MARC map “Stitle”. |
Description |
Enter a description of the MARC map. For example, for a Title Keyword index, you could enter “Title Keywords”. |
Clear this box. This option is for Search Limiting MARC maps only. |
|
Leave the No Filter option marked. |
|
2 | In these fields, do the following: |
Field |
Action |
||||||
Tag |
Enter the tags you want the MARC map to extract information from. For example, if you are creating a keyword indexing MARC map to extract title information, your first extraction tag would be “245”. This is an example of the extraction tags and subfields for a MARC map used for a standard Title Keyword index:
|
||||||
Part |
Enter the subfields or fixed field positions of the tag you want the MARC map to extract information from. |
||||||
If you want to set a condition on the tag you are extracting, enter which part (subfield or fixed field position) must contain the conditional value in order for Horizon to extract the MARC information. Note: Entering conditions requires that you specify characters, such as the slash ( / ) before a fixed field position, and so forth. (For a list of conditional characters, see Conditional MARC Map Syntax. For an example of how a conditional character can be used, see Example of a MARC Map with Conditionals .) |
|||||||
If you want to set a condition on the tag you are extracting, enter the value the conditional part (subfield or fixed field position) must contain in order for Horizon to extract the MARC information. |
|||||||
Do one of these options:
Note: If you mark this option, you must make sure the Do Not Run-on option is also marked for this MARC map.
|
Note: Leave the other fields in this screen blank.
Note: In this title keyword index example, there are no conditions set on the entire map. This is because you want to extract all title tags without any conditions. As a result, this example includes no entries in the Conditional group on the last page of the marc_map view. Depending on what type of keyword index you are creating, you may or may not need to set conditions on your entire MARC map. (For complete information on conditional parts of a MARC map, see Understanding Conditional Parts of a MARC Map.)
