Subject [jira] [Created] (LUCENE-4096) impossible to CheckIndex if you use norms other than byte[]
Date Thu, 31 May 2012 04:11:25 GMT
Robert Muir created LUCENE-4096:

             Summary: impossible to CheckIndex if you use norms other than byte[]
                 Key: LUCENE-4096
             Project: Lucene - Java
          Issue Type: Task
          Components: core/index
    Affects Versions: 4.0
            Reporter: Robert Muir
             Fix For: 4.0

I noticed TestCustomNorms had the checkIndexOnClose disabled, but
I think this is a real problem.

If someone wants to use e.g. float[] norms, they should be able to run

CheckIndex is fine with validating any norm type, the problem is that it sometimes creates
an IndexSearcher and fires off TermQueries for some calculations. This causes it to (wrongly)
fail, because DefaultSimilarity expects single byte norms.

I don't think CheckIndex needs to use TermQuery here, we can do this differently so it doesnt
use IndexSearcher or TermQuery but just the postings apis.
