Re: Indexing LDAP entries

Hi josh,

Thanks for the reply.

I now understand index type sub and its family of indexes.
But I am still very unclear about the other types, here is 
what I think they are and their usage, please correct me 
where I am wrong:

eq : maintain an index for exact matches. so I suppose 
it is only used if the filter pattern does not use wildcards.

pres : maintain an index for presence of attributes for any

approx : approximate index, what is it, how will it be used, 
and for what sort of search filters?

sub : consists of subinitial, subany, subfinal. Can i just specify
"sub" as an index type, or does it have to be 1 of the above?
