Robert Muir updated LUCENE-3723:
--------------------------------
Attachment: LUCENE-3723_test.patch
I'd really like to commit these asserts, but this query is in the way.
As a temporary measure we can @Ignore its tests.
> Remove FieldMaskingSpanQuery (or fix its scoring)
> -------------------------------------------------
>
> Key: LUCENE-3723
> URL: https://issues.apache.org/jira/browse/LUCENE-3723
> Project: Lucene - Java
> Issue Type: Bug
> Affects Versions: 4.0
> Reporter: Robert Muir
> Attachments: LUCENE-3723_test.patch
>
>
> In Lucene 4.0 we added new scoring mechanisms, but FieldMaskingSpanQuery is a
> serious problem:
> Because it lies about the fields of its terms, this sometimes results in
> totally bogus
> statistics, cases where a single terms totalTermFreq exceeds sumTotalTermFreq
> for the entire field (since its lying about it).
> Such lying could result in NaN/Inf/Negative scores, exceptions, divide by
> zero, and other problems,
> because the statistics are impossibly bogus.
