Subject [jira] Commented: (LUCENE-1260) Norm codec strategy in Similarity
Date Mon, 22 Jun 2009 12:16:07 GMT


Karl Wettin commented on LUCENE-1260:

Hi Johan,

didn't try it out yet but the patch looks nice and clean. +1 from me. Let's try to convince
some of the old -1:ers. 

YONIK? See, it's not just me. ; )

I do however still think it's nice with the serializable codec interface as in the previous
patches in order for all applications to use the index as intended (Luke and what not). 256
bytes stored to a file and by default backed by a binary search or so unless there is a registred
codec that handles it algorithmic. I'll copy and paste that in as an alternative suggestion

(I think the next move should be to allow for per field variable norms resolution, but that
is a whole new issue.)
