Like the Keyword search, fielded searching in the database will treat any terms separated by a space as an "AND" search and will retrieve all records which have both terms in the selected field in any order. This field contains information about the period, dynasty, ruler, and/or calendar-like dates associated with the object at the time it was created. Examples: Old Kingdom Period, Dynasty 4, King/Ruler Khafre, dates 2558 BC-2532 BC is an example of a complete record. The dating fields are currently under revision and some fields may contain duplicate information. Most of the records contain no information in the Date or King/Ruler field at this time.
