Soap search admin mode

[lfasci]

Hi

I'm using search.pl to make zimbra search using perl and soap
it works well, I need to know if I can make search on users
messages using ahe admin account.

For example :

user a has a message about "blabla"
user b has two messages about "blabla"

using admin account I want to search for "blabla"
and have the messages from a and b

Is this possible ? how ?

Thank You
