B.4.1.1.4. Using a Language Tag and Suffix for the Matching Rule
As an alternative to using a relational operator-value pair, append a suffix that represents a specific
operator to the language tag in the matching rule portion of the filter. Combine the language tag and
suffix as follows:
attr: language-tag+suffix := value
For example, to search for all surnames that come at or after
La Salle
in the French collation order,
use the following filter:
sn:fr.4:=La Salle
For a list of locales supported by the Directory Server and their associated language tags, see
Table D.1, “Supported Locales”
. For a list of relational operators and their equivalent suffixes, refer to
Table B.3, “Search Types, Operators, and Suffixes”
.
B.4.1.2. Using Wildcards in Matching Rule Filters
When performing a substring search using a matching rule filter, use the asterisk (*) character as a
wildcard to represent zero or more characters.
For example, to search for an attribute value that starts with the letter
l
and ends with the letter
n
, enter a
l*n
in the value portion of the search filter. Similarly, to search for all attribute values
beginning with the letter
u
, enter a value of
u*
in the value portion of the search filter.
To search for a value that contains the asterisk (*) character, the asterisk must be escaped
with the designated escape sequence,
\5c2a
. For example, to search for all employees with
businessCategory
attribute values of
Example*Net product line
, enter the following value in
the search filter:
Example\5c2a*Net product line
B.4.2. Supported Search Types
The Directory Server supports the following types of international searches:
• equality (=)
• substring (*)
• greater-than (>)
• greater-than or equal-to (>=)
• less-than (<)
• less-than or equal-to (<=)
Approximate, or phonetic, and presence searches are supported only in English.
As with a regular
ldapsearch
search operation, an international search uses operators to define the
type of search. However, when invoking an international search, either use the standard operators
