matching rule

A matching rule is a schema element that defines how the server should interact with values of an attribute. There are three standard types of matching rules:

In addition to these standard matching rules, the directory server defines a fourth type, approximate matching rules, which are used to determine whether one value is approximately equal to another. The definition of “approximately equal to” can vary, but one common use is “sounds like”.

Common examples of matching rules include:

booleanMatch

An equality matching rule that determines whether two Boolean values are equal to each other.

caseExactMatch

An equality matching rule that determines whether two string values are equal to each other, without ignoring differences in capitalization.

caseExactOrderingMatch

An ordering matching rule that is used to determine the relative order between two string values, without ignoring differences in capitalization.

caseExactSubstringsMatch

A substring matching rule that is used to determine whether a string value contains a given substring, without ignoring differences in capitalization.

caseIgnoreMatch

An equality matching rule that determines whether two string values are equal to each other, ignoring differences in capitalization.

caseIgnoreOrderingMatch

An ordering matching rule that is used to determine the relative order between two string values, ignoring differences in capitalization.

caseIgnoreSubstringsMatch

A substring matching rule that is used to determine whether a string value contains a given substring, ignoring differences in capitalization.

distinguishedNameMatch

An equality matching rule that determines whether two distinguished name are equal to each other, ignoring extra spaces around commas separating RDN components and equal signs separating RDN names from values. The individual RDN values will be compared based on the matching rules associated with the corresponding RDN attributes.

generalizedTimeMatch

An equality matching rule that determines whether two generalized time values are equal to each other.

generalizedTimeOrderingMatch

An ordering matching rule that is used to determine the relative order between two generalized time values.

integerMatch

An equality matching rule that determines whether two integer values are equal to each other.

integerOrderingMatch

An ordering matching rule that is used to determine the relative order between two integer values.

octetStringMatch

An equality matching rule that determines whether two values are exactly equal to each other using a byte-for-byte comparison.

In most cases, the directory server will use matching rules in a completely “behind the scenes” manner without the client needing to know about it. Whenever the client references a given attribute type, then the server will automatically know to use the appropriate matching rules for that attribute. However, it is also possible for the client to request that the server use a specific matching rule when performing an operation through the use of an extensible match filter.

The set of matching rules defined in the server may be determined by retrieving the matchingRules attribute of the subschema subentry. For more information about matching rules, see Understanding Matching Rules in Sun OpenDS Standard Edition 2.2 Architectural Reference.
