Name Lookup for secondary Address book

Got user name in the format of first name, last name, name, email in CSV format. Imported into Secondary address book, was was created from pubnames.nsf. Enabled the directory assistance & restarted the server.

In Server Console : input the command “show xdir”

Got the both domino directoryies.

My Question : After I created the mail, looking for a name in the secondary address book, the email is not able lookup. I can see the objects (email using “show details”).

How should I enable the lookup for the secondry domino address book.
