Subject [jira] [Commented] (LUCENE-3607) Lucene Index files can not be reproduced faithfully (due to timestamps embedded)
Date Wed, 30 Nov 2011 12:45:40 GMT


Robert Muir commented on LUCENE-3607:

Is that "analyzer binding to content vs. binding to search" issue known and discussed at Lucene
already ? 

No, because its eclipses bug. you can set analyzers however you want in lucene, we don't enforce

And, why does the German analyzer truncate words at "." while the US one does not (See [])

Because you are using an ancient version of lucene.

> Eclipse 3.7 uses Lucene 2.9.1 for indexing online help content. A pre-generated help
index can be shipped together with online content. As per
>    [[ ]]
> it turns out that the help index can not be faithfully reproduced during a build, because
there are timestamps embedded in the index files, and the "NameCounter" field in segments_2
contains different contents on every build.
> Not being able to faithfully reproduce the index from identical source bits undermines
trust in the index (and software delivery) being correct.
> I'm wondering whether this is a known issue and/or has been addressed in a newer Lucene
version already ?
