Red Hat DIRECTORY SERVER 7.1 - ADMINISTRATOR Administrator's Manual page 601

You can use the collation order OID in the matching rule portion of the matching
rule filter as follows:
attr:OID:=(relational_operator value)
The relational operator is included in the value portion of the string, separated
from the value by a single space. For example, to search for all
attributes that are at or after
following filter:
departmentNumber:2.16.840.1.113730.3.3.2.46.1:=>= N4709
Using a Language Tag for the Matching Rule
Each locale supported by the directory server has an associated language tag. For a
list of locales supported by the directory server and their associated language tags,
see Table D-1, on page 615.
You can use the language tag in the matching rule portion of the matching rule
filter as follows:
attr:language-tag:=(relational_operator value)
The relational operator is included in the value portion of the string, separated
from the value by a single space. For example, to search the directory for all
description attributes with a value of
order, use the following filter:
cn:es:== estudiante
Using an OID and Suffix for the Matching Rule
As an alternative to using a relational operator-value pair, you can append a suffix
that represents a specific operator to the OID in the matching rule portion of the
filter. Combine the OID and suffix as follows:
attr:OID+suffix:=value
For example, to search for
softwareproduckte
businessCategory:2.16.840.1.113730.3.3.2.7.1.3:=
The in the previous example is the equality suffix.

For a list of locales supported by the directory server and their associated OIDs, see
Table D-1, on page 615. For a list of relational operators and their equivalent
suffixes, see Table B-3, on page 603.
