[389-users] Optimising queries

[jim at scusting.com]

Hi,  I have some queries which are showing in the logs as not being 
indexed (notes=U right?).  In the example below the accountid is indexed 
but the authrole is not, but I would of expected the query to use the 
accountid index?

conn=308 op=1 SRCH base="o=blah.com" scope=2 
filter="(&(accountid=abc123)(authrole=PowerUser))" attrs=ALL
conn=308 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U

Do I need to index the authrole attribute as well in order for the 
indexes to be used on a query like this?  If I need to add indexes for 
anything that maybe in included in an & LDAP query, and indexes for 
anything that may require sorting on (my previous post) then I'll end up 
with indexes for just about everything!

Can anyone recommend any good sites & tools for explaining LDAP queries 
and indexing?  I did some searching but not found anything usefull which 
explains why the above would not be indexed.  I have previously used 
MySQL and I'm sure the above equivalent which just use the accountid 
index and not worry about the authrole not being indexed.

Thanks.

Jim.
