description: Manufacturing lead for the Z238 line.
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 “Bill” and “Bill Pumice”.
2.
Create the appropriate common name approximate index entries for “Bill” and
“Bill Pumice”.
3.
Create the appropriate common name substring index entries for “Bill” and
“Bill Pumice”.
4.
Create the surname equality index entry for “Pumice”.
5.
Create the appropriate surname approximate index entry for “Pumice”.
6.
Create the appropriate surname substring index entries for “Pumice”.
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.
