Netscape DIRECTORY SERVER 6.1 - ADMINISTRATOR Administrator's Manual page 353

See Netscape Directory Server Configuration, Command, and File Reference for further
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.
NOTE The metaphone phonetic algorithm in Directory Server supports
only US-ASCII letters. Therefore, use approximate indexing only
with English values.
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:
Name in the directory
(Phonetic code)
Alice B Sarette
(ALS B SRT)
Query string Match comments
(Phonetic code)
Alice Sarette Matches. Codes are specified in the correct
(ALS SRT) order.
Alice Sarrette Matches. Codes are specified in the correct
(ALS SRT) order despite the misspelling of Sarette.
Surette Matches. The generated code exists in the
(SRT) original name despite the misspelling of
Sarette.
Bertha Sarette No match. The code BR0 does not exist in
(BR0 SRT) the original name.
Sarette, Alice No match. The codes are not specified in
(SRT ALS) the correct order.
