Specifying a Condition for Special Fields
When you specify search criteria, you can enter a special field such as HOLD or LINK REC in the Field search parameter.
To choose to retrieve records in which a special field exists, enter the special field in the Field search parameter and enter 'e' ("exist") in the Condition search parameter. For example, to create a review file containing bibliographic records that have title-level holds on them, enter the following in the Boolean Search window:
Search parameter | Enter: |
---|---|
Type | b |
Field | 8 |
Condition | e |
The system displays the line:
BIBLIOGRAPHIC HOLD exist
Some special fields can contain a value. You can search for records that contain a specific value in a special field. For example, to create a review file containing bibliographic records that are linked to order records, enter the following in the Boolean Search window:
Search parameter | Enter: |
---|---|
Type | b |
Field | ^ |
Condition | e |
Value A | o |
The system displays the line:
BIBLIOGRAPHIC LINKED REC exists to ORDER
Some special fields can output with additional information. For example, the ITEM ID field of course records outputs the TITLE, AUTHOR, and LOCATION from the bibliographic record, as well as the item record number and the TOT CHKOUT field value:
Search parameter |
Enter: |
---|---|
Type | r |
Field | 9 |
Here is an example of the output when listing ITEM ID fields in course records:
Caterpillar, caterpillar French, Vivian Children's Roo QE 595.78 FRENCH 39 i11841229
You can also search for records that do not contain a specific special field (or that do not contain a specific value in a special field). Enter the special field in the Field search parameter and enter 'n' ("not exist") in the Condition search parameter. (To retrieve records that do not contain a specific value in a special field, enter the value in the Value A search parameter.) For example, to create a review file containing bibliographic records that are not linked to item records, enter the following in the Boolean Search window:
Search parameter | Enter: |
---|---|
Type | b |
Field | ^ |
Condition | n |
Value A | i |
The system displays the line:
BIBLIOGRAPHIC LINKED REC not exist to ITEM
The Special COURSE ID Field
When you select the special COURSE ID field, the system functions differently than with the other special fields. Instead of retrieving item records that contain or do not contain COURSE ID fields, the system creates a review file of items that contain the course number you specify. After you enter '=', the system prompts you to enter the course number for which you want to search.
