---------------------------------
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?

> 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 no docs have a value
> - if the missing value is 0
