Search Limiting MARC maps let staff or borrowers narrow a list of search term matches as they search. They can use limiting to “weed out” unwanted matches in a keyword search after you have started the search. (For example, if you do a title keyword search for the word “computers,” Horizon lists several titles. If you want only the latest information on computers, you can limit the search date by choosing “publication date” as the field option, selecting “greater than” as the limiting operator, and entering “2001” as the limiting value. Horizon regenerates the list, showing only those titles published after 2001.)
When you set up search limiting options, staff searching displays these options in the Search Limit window when users click Limit from a Titles List window:
Information Portal also uses Limiting MARC Maps to help limit your searching. (For more information about changing limiting options and the Limiting MARC maps that Information Portal uses, see the Information Portal System Administrator’s Guide.)
