Maybe I'm missing something, but that looks like the correct order to me, they are both on September 02, 2007, 11:30 P.M, and ]24 seconds is before 48 seconds. Or is it just late and I'm missing the obvious (a specialty of mine)... Erick On 10/18/07, Dragon Fly <[EMAIL PROTECTED]> wrote: > >

Re: Sort by date THEN by relevancy

Erick, Ouch!! Please excuse the cut-n-paste ;) LIA mentions a lot about performance when doing sorting. Is it something to be cautious about? You mention doing 5 fields and it works ok, ... can share with us how many documents you are handling there with 5 fields ? Thanks. ~KEGan On 9/29/06,
