Re: does one need to reindex when changing similarity class

Yes, if the replacing similarity has a different implementation on norms, you should reindex or gradually update all documents within decent time. -Original message- From:Ahmet Arslan iori...@yahoo.com.INVALID Sent: Thursday 9th October 2014 18:27 To: solr-user@lucene.apache.org Subject: Re: does one need to reindex when changing similarity class How about SweetSpotSimilarity?

I've read somewhere that we do have to reindex when changing similarity class. Is that right? Thanks again, Elisabeth

The similarity class is only invoked at query time, so it doesn't participate in indexing. -- Jack Krupansky -Original Message- From: Markus Jelsma Sent: Thursday, October 9, 2014 6:59 AM To: solr-user@lucene.apache.org Subject: RE: does one need to reindex when changing similarity class Hi - no you don't have to, although maybe if you changed on how norms are encoded.

Re: does one need to reindex when changing similarity class
How about SweetSpotSimilarity? Length norm is saved at index time?
