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=0.002000RM> It's exactly the same search? Same base, scope, and filter? Yes. Exactly the same. The only difference is the search control for server-side sorting over sn. With this control : [09/Dec/2008:16:55:59 +0100] conn=3826 op=3 SORT sn;2.16.840.1.113730.3.3.2.11.1 (59) [09/Dec/2008:16:55:59 +0100] conn=3826 op=3 RESULT err=0 tag=101 nentries=40 etime=0.004000 notes=U
Ok. I'm not sure what's going on then.
