Red Hat Directory Server 8.0 Administrator's Guide

• Equality, approximate, and substring indexes for cn (common name) and sn (surname)
attributes.
• Equality and substring indexes for the telephone number attribute.
• Substring indexes for the description attribute.
When adding that entry to the directory, the Directory Server must perform these steps:
1. Create the cn equality index entry for John and John Doe.
2. Create the appropriate cn approximate index entries for John and John Doe.
3. Create the appropriate cn substring index entries for John and John Doe.
4. Create the sn equality index entry for Doe.
5. Create the appropriate sn approximate index entry for Doe.
6. Create the appropriate sn substring index entries for Doe.
7. Create the telephone number equality index entry for 408 555 8834.
8. Create the appropriate telephone number substring index entries for 408 555 8834.
9. Create the appropriate description substring index entries for Manufacturing lead for the
Z238 line of widgets. A large number of substring entries are generated for this string.
As this example shows, the number of actions required to create and maintain databases for a
large directory can be resource-intensive.
2. Creating Indexes
This section describes how to create presence, equality, approximate, substring, and
international indexes for specific attributes using the Directory Server Console and the
command-line.
NOTE
Because Directory Server 8.0 can operate in either a single or multi-database
environment, remember to create new indexes in every database instance since
newly-created indexes are not automatically created in the other databases.
However, the same is not true for default indexes because they are automatically
present and maintained in subsequent database instances but not added to
existing ones. In other words, the directory uses the most recently-created set of
default indexes in subsequent databases. This means that if you add a default
