Attribute Equality Index

An equality index is a type of index that is used to identify efficiently which entries are exactly equal to a given assertion value. An equality index may only be maintained for attributes that have a corresponding equality matching rule. That matching rule will be used to normalize values to use as index keys, and the value for that key will be the ID list containing the entry ID of the entries with values that are equal to that normalized value.
