Restriction
|
Enter a code that refers to the restriction criteria you are setting up.
For example, if you want the option to search only periodicals, you would enter “per”. To search only fiction materials, you might enter “fic”.
|
Description
|
Enter a description for the restriction criterion.
For example, you might enter “Periodicals (collection)” as the description for the Restriction “per”.
|
Definition
|
Enter the group information for Ord, Item Table Column, Exclude, and Value(s) for each restriction criterion.
Each new group entry creates a more specific restriction. Depending on the restriction you are defining, you may need to enter more than one group entry. (For example, if the restriction is periodicals, you only need one group entry. If the restriction is paperback fiction, you need two group entries—one for fiction and one for paperbacks.)
|
Ord
|
Enter the order in which each restriction is listed within the restriction set.
You should give the most specific restriction the first order, and give the least specific restriction the last order. If the restriction has more than one group entry, each entry must have a unique ord number.
|
Item Table Column
|
Enter the name of the column in the Item table that Horizon restricts by. (For example, if the restriction is the Periodicals collection, you would enter “collection”. If the restriction is to an item type of paperback, you would enter “item_type”.)
Note: These are the columns in the item table that you can restrict by: call_type, collection, item_status, itype, location, saved_collection, saved_itype, saved_location, and withdraw_instruction.
|
Exclude
|
Do one of these options:
|
•
|
If you want to search everything for this restriction except the criterion you are setting up, mark Exclude. |
|
•
|
If you want the criterion you are setting up to be included in the search, mark Include. |
For example, to restrict a search to fiction but not paperback fiction, mark Include in the fiction group entry and mark Exclude in the paperback group entry.
|
Value(s)
|
Enter all possible values that an item can have to qualify as a match for the restriction. You must enter valid codes based on what you entered in the Item Table Column field.
For example, if you entered “itype” in the Item Table Column field and you want to restrict the search to audio and visual materials, enter the item circulation types (ITYPEs) on your system for audio and visual materials. For example, enter “‘av’,’vid’”.
Note: Each code must be enclosed in single quotes. You can enter two or more values by enclosing each value in single quotes, separated by a comma placed outside the quotes (for example, ‘fic’,‘hist’). You can combine multiple values for the same criterion in a single string, but you cannot combine multiple values for different criteria in the same string. (For example, you can create a criterion for collection and include the values fiction and history, but you cannot combine a collection with a status such as ‘fic’,‘in’.)
