[Evolution] Need help for Evolution LDAP search

[Henry Jia <Henry Jia sun com>]

[Send for Steven Zhang. His mail box encounts some problem.]

Folks, 

I met some problem in using Evolution 1.4.5 under redhat.
When I start evolution, and try to search contact in LDAP, I found  EVO 
provides the following LDAP search features:
1, search by name
2, search by email
3, search by category
4, any field contains
5, advanced search

1 and 2 works very well. But I have no idea about 3, how "search by 
category" works? I select some category, and click search, but it seems 
return nothing.
And to 4, "any field contains", if I input a name or email, it works, 
but if I input a phonenumber or postal address, it return nothing, does 
any field means only match name or email?

About advanced search, I found I can create some filter expression, but 
the selectable field I can select is only name/email/category and 
expression. How expression work, I try to read the help document, but 
found nothing about this. Anyway, I tried to input a expression like 
cn=*steven*, but it seems does not work.

Anybody can help me here?
