ABSTRACT:
A computer-implemented method of indexing an electronic database record to facilitate searching is provided, as well as a method of performing a search using the index. The method includes receiving a value for one of a start field and an end field for a database record that defines a validity range for a property. The method further includes assigning a corresponding one of multiple defined index values for the received value. There is a different index value defined for each of multiple defined consecutive ranges for the property. The assigned index value corresponds to a one of the multiple defined consecutive ranges within which the received value falls. The method also includes storing the assigned index value in association with the database record in a manner that is searchable.
