Definition: Less Than Or Equal To Search Filter
An less or equal search filter is a type of search filter that can be used to identify entries that contain a specific value for a given attribute that is less than or equal to the provided assertion value. The server will use an ordering matching rule to make the determination.
The string representation of an LDAP less or equal search filter is comprised of an opening parenthesis followed by the attribute name, a less than sign, an equal sign, the assertion value, and the closing parenthesis. For example, a less or equal filter of "(createTimestamp<=20070101000000Z)" will match any entry that has a createTimestamp value that is less than or equal to "20070101000000Z".
