Adrien Grand updated LUCENE-5837:
---------------------------------
Attachment: LUCENE-5837.patch
Here is a patch.
Do we have a benchmark that could be used to validate this change? I just
checked out luceneutil but it only seems to have tasks for queries, not sorting?
> Only check docsWithField when necessary in numeric comparators

> Our numeric comparators have branches to deal with missing values. However
> there are some cases when checking docs that have a field is not useful:
> - if all docs have a value
> - if no docs have a value
> - if the missing value is 0
