Re: does one need to reindex when changing similarity class
To correct myself, the selected Similarity class can have a computeNorm method that calculates the "norm" value that will be stored in the index when the document is indexed, so changing the Similarity class will require reindexing if the implementation of the computeNorm method is different. -- Jack Krupansky -Original Message- From: Markus Jelsma Sent: Monday, October 13, 2014 5:06 PM To: solr-user@lucene.apache.org Subject: 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 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?

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 > 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?

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

Re: does one need to reindex when changing similarity class
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.

Is that right? Thanks again, Elisabeth

Hi - no you don't have to, although maybe if you changed on how norms are encoded.
