Michael McCandless commented on LUCENE-1714:
--------------------------------------------
Looks good! Shai, can we pre-compile the regex up front
(java.util.regex.Matcher) so we don't have to compile it three times on every
written line?
> WriteLineDocTask incorrectly normalizes fields

> Key: LUCENE-1714
> URL: https://issues.apache.org/jira/browse/LUCENE-1714
> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/benchmark
> Reporter: Shai Erera
> Assignee: Michael McCandless
> Fix For: 2.9
>
> Attachments: LUCENE-1714.patch
>
>
> WriteLineDocTask normalizes the body, title and date fields by replacing any
> "\t" with a space. However, if any one of them contains newlines,
> LineDocMaker will fail, since the first line read will include some of the
> text, however the second line, which it now expects to be a new document,
> will include other parts of the text.
> I don't know how we didn't hit it so far. Maybe the wikipedia text doesn't
> have such lines, however when I ran over the TREC collection I hit a lot of
> those.
> I will attach a patch shortly.
