Review comment:
Again, just drop "testSplitOnWhitespace_" from the method name, I think.

Review comment:
It appears this change (the addition of MatchNoDocsQuery here) has no
effect but maybe I'm mistaken?

Review comment:
Based on the test name, I'd expect sow=true each time. Maybe just drop
this part of the method name.

Review comment:
In essence, I think the behavior I see here was correct *before* -- no
special case for either StrField or numerics. In the context of the logic that
reaches this point, the field is already ft.isTokenized==false.

Review comment:
This is a change in behavior, and I think it's not a good change. For a
non-tokenized field (StrField in this case), I think we should ignore whatever
"sow" is and split on whitespace any way, thus here have two terms to match.
It would be straight-forward to document this (no differences between numbers
and StrField).
I think it could be reasonable to try both ways (both split and don't split)
and then put a DisjunctionMaxQuery over the two, though I'd prefer not.
