Re: index-time boost ... query
No, the reverse is true. Sorting is very very fast in Lucene. The first sort operation spends a lot of time making a data structure and then following sort calls use it.

Re: index-time boost ... query
Hi David, I just now tried a sorting on the results and I got the records with latest approval_dt first. My question now is will index-time boosting method increase the response. ie will I be able to acheive the same thing i achieved using sorting much faster if i use index-time boosting. If you feel it helps could you please send me a sample query also. Thanks, Anil.

Re: index-time boost ... query
Hi David, Thank you for the mail. It seems you are right.sorting might solve the issue as it is not giving any special weightage to any record other than its approval_dt is the latest one.. I think i am convinced for now. I am eagerly waiting for your book around thanks giving so taht i can spend 4 days completely on it. I am fascinated by SOLR and what to master it ASAP. Best Rgds, Anil. On Thu, Nov 19, 2009 at 3:36 PM, Smiley, David W. wrote: > Anil, without delving into why your boosting isn't working as you expect, > why don't you simply sort?

Re: index-time boost ... query
Anil, without delving into why your boosting isn't working as you expect, why don't you simply sort? Based on a message you sent to me directly (excerpted bellow), it seems you want sorting, not boosting. You could subsequently sort by score after approval_dt. ~ David Smiley Author: http://www.packtpub.com/solr-1-4-enterprise-search-server/ > > My ultimate aim is to always bring up records in the result having latest > approval_dt to appear first using index-time boosting in SOLR.
