information about these attributes.
In addition, the directory uses a variation of the metaphone phonetic algorithm to
perform searches on an approximate index. Each value is treated as a sequence of
words, and a phonetic code is generated for each word.
Values entered on an approximate search are similarly translated into a sequence
of phonetic codes. An entry is considered to match a query if both of the following
are true:
• All of the query string codes match the codes generated in the entry string.
• All of the query string codes are in the same order as the entry string codes.
For example:
NOTE The metaphone phonetic algorithm in Directory Server supports
only US-ASCII letters. Therefore, use approximate indexing only
with English values.
