Further suppose that the Directory Server is maintaining the following indexes:
• Equality, approximate, and substring indexes for common name and surname
attributes
• Equality and substring indexes for the telephone number attribute
• Substring indexes for the description attribute
Then to add this entry to the directory, the Directory Server must perform these
steps:
1.
Create the common name equality index entry for
John
and
John Doe
.
2.
Create the appropriate common name approximate index entries for
John
and
John Doe
.
3.
Create the appropriate common name substring index entries for
John
and
John Doe
.
4.
Create the surname equality index entry for
Doe
.
5.
Create the appropriate surname approximate index entry for
Doe
.
6.
Create the appropriate surname substring index entries for
Doe
.
7.
Create the telephonenumber equality index entry for
408 555 8834
.
8.
Create the appropriate telephonenumber substring index entries for
408 555
8834
.
9.
Create the appropriate description substring index entries for
Manufacturing
lead for the Z238 line of widgets
. A large number of substring entries
are generated for this string.
The example shows that indexing can be costly.
