Re: does one need to reindex when changing similarity class

2014-10-13 Thread Jack Krupansky
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.

Yes, if the replacing similarity has a different implementation on norms, 
you should reindex or gradually update all documents within decent time.

How about SweetSpotSimilarity? Length norm is saved at index time?

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

should reindex or gradually update all documents within decent time.

The similarity class is only invoked at query time, so it doesn't 
participate in indexing.

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

Thanks again,
