I tried full GeneralizedTime format (with seconds, with fractions) but the search works also slow. Even the search (|(logTime=20120920144001+0400)(logTime=20120920144008+0400)) that works less than second and returns 2 entries, when reformatted as (&(logTime>=20120920144001+0400)(logTime<=20120920144008+0400)) works more than 50 seconds. According to RFC4517 ( http://tools.ietf.org/html/rfc4517#section-3.3.13), GeneraalizedTime has the syntax: GeneralizedTime = century year month day hour [ minute [ second / leap-second ] ] [ fraction ] g-time-zonewhich means that minutes and seconds may be omitted. Probably that's not implemented... no problem. openldap version 2.4.23 How may I optimize (&(>=)(<=)) searches? -- WBR, Roman Rybalko |
