No, it does not seem to be sufficient. I have activated all the
indexes for the attribute (sn), the logs still show "notes=U" :
[09/Dec/2008:16:36:38 +0100] conn=3817 op=3 RESULT err=0
tag=101 nentries=40 etime=0.004000 notes=U
...
Maybe there is a special type of index for server-side sorting
like
the one for the VLV?
No.
Do you have any problems if you search on those attributes without
server side sorting?
No, not really. It's more a request from our developers to simplify
user sorting in their web applications.
If i make the same search without the sorting the result is shown as
indexed (no "notes=U") and takes two times less time :
[09/Dec/2008:16:48:58 +0100] conn=3821 op=3 RESULT err=0 tag=101
nentries=40 etime=0.002000
It's exactly the same search? Same base, scope, and
filter?
