This section clarifies what Horizon does in staff searching when you use the Equal To operator to limit dates.
After you choose a search option and enter a search term, Horizon displays a list of records that match your search criteria. You can then choose to limit the list of titles using a limiting operator. (For example, you may want to limit the titles by publication date.) When you use the equal to ( = ) operator, Horizon finds a hit if the date value lies within a range of dates included in the date field in the MARC record. Horizon then arranges the years in sequence.
For example, if the date range in the MARC record is “[1997], c1959”, Horizon processes the information as “19591997”. As a result, a title with a publication date of “1988” falls within that date range. A publication date of “19--” also matches the search criteria because Horizon considers the dashes to be wildcards.
