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: > >

Hi, I'm am trying to sort a date field in my index but I'm seeing strange results. I have searched the Lucene user mail archive for Datetools but still couldn't figure out the problem. The date field is indexed as follows (i.e. DateTools is used, date field is stored and untokenized): Strin

Avoiding sort by date

Hi folks, I am using Lucene 2.0 In our application, I am indexing a stream of documents. Each document is fairly small (< 1 KB), but there can be 10's of millions of documents. Each document has a Timestamp field. Users can enter free-form searches and a date/time range. They are most interest

Re: Sort by date THEN by relevancy

Sorting will inevitably have an impact on your speed, but it's impossible to generalize. FWIW, my app has 870K documents, the index is around 1.4G and search/sort times are fine. But even that statement is misleading. "Fine" means that the product manager for this product is satisfied with perform

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,

Hi, I have seen some sort examples in LIA. But cant find what I am looking for. How do I sort document by date, AND for all the documents with the same date ... these are sorted by relavency. (Date has higher sort priority in this case). Thanks.
