Re: [389-users] Server side sort not using index

Hi,
I noticed in our directory server logs a number of queries which are not
using indexes, and this appears to be down to sorting of the query being
done the server side:
----- Server sorted-------------
conn=1433 op=1 SRCH base="o=blah.com" scope=2
filter="(&(accountid=abc123)(objectClass=dnszone)(dnstype=soa))" attrs=ALL
conn=1433 op=1 SORT dnszonename (4)
conn=1433 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U
----- Not sorted ----------
conn=1440 op=1 SRCH base="o=blah.com" scope=2
filter="(&(accountid=abc123)(objectClass=dnszone)(dnstype=soa))" attrs=ALL
conn=1440 op=1 RESULT err=0 tag=101 nentries=1 etime=0
The 'accountid' field is indexed but when doing server side sorting it
seems to ignore this index - is this expected behaviour? What options
do I have to ensure the index is used - just get the developers to sort
the results in their code rather than on the server?
I think the problem is that the attribute dnszonename is not indexed.
Thanks.
Jim.
