13.5. Changing the Index Sort Order
By default, indexes are sorted alphabetically, in descending ASCII order. This is true for every attribute, even attributes which may have numeric attribute values like Integer or TelephoneNumber. It is possible to change the sort method by changing the matching rule set for the attribute.
13.5.1. Changing the Sort Order Using the Command Line
To change the sort order using the command line, change the
nsMatchingRule
for the attribute index. For example:
# ldapmodify -D "cn=Directory Manager" -W -x dn: cn=sn,cn=index,cn=Example1,cn=ldbm database,cn=plugins,cn=config changetype:modify replace:nsMatchingRule nsMatchingRule: integerOrderingMatch
