Index data is maintained in a first index of current data objects and in a second index of aged data objects. A database management system may categorize data objects as either current or aged based either on processes associated with the data objects or based upon time. The database management system may later re-categorizing the data object to reflect changes in processes or time. The database management system may receive a query for data and first search the index of current data objects, then search the index of aged data objects.
