Field Codes are a specific part of a record in a database. Some of the most common fields that can be used in database searching include author, title, subject, and abstract.
Look for drop down boxes or menus to select in a database to select the field you want to search. The default field for most databases is usually keyword or all fields. By keeping this default, the database will search in any indexed field. But using specific field codes in combination with other search techniques can produce more precise searches.
