Should I really add an index for modifyTimestamp? I got "slapd[4021]: <= bdb_inequality_candidates: (modifyTimestamp) not indexed!" (No discussions on using BDB, please!)
The pure log message does not say much. It depends on the real filters used whether you should index an attribute or not. Hint: You can make *search* performance worse with more indexes.
Ciao, Michael.
P.S.: The log message is not helpful and e.g. with my Æ-DIR it's itself a performance hog (see ITS#7796)
