The are used to store information that makes it possible to locate entries very quickly when processing search operations. Indexing is performed on a per-attribute level and different types of indexing may be performed for different kinds of attributes based on how they are expected to be accessed during search operations. ds-cfg-local-db-index top This specifies the name of the attribute for which the index is to be maintained. ds-cfg-attribute This specifies the maximum number of entries that will be allowed to match a given index key before that particular index key is no longer maintained. This is analogous to the ALL IDs threshold in the Sun Java System Directory Server. If this is specified, it will override the JE backend-wide configuration. For no limit, use 0 for the value. If any index keys have already reached this limit, indexes will need to be rebuilt before they will be allowed to use the new limit. Number of entries ds-cfg-index-entry-limit This specifies the type(s) of indexing that should be performed for the associated attribute. For equality, presence, and substring index types, the associated attribute type must have a corresponding matching rule. If any new index types are added for an attribute and there are values for that attribute which already exist in the database, then the index will need to be rebuilt before it will be accurate. This index type will be used to help improve the efficiency of searches using equality search filters. This index type will be used to help improve the efficiency of searches using "greater than or equal to" or "less then or equal to" search filters. This index type will be used to help improve the efficiency of searches using the presence search filters. This index type will be used to help improve the efficiency of searches using substring search filters. This index type will be used to help improve the efficiency of searches using approximate matching search filters. ds-cfg-index-type The length of substrings in a substring index. The index will need to be rebuilt before it will reflect the new value. 6 ds-cfg-substring-length
