Hi Stephen,
I have the same scenario with you. I verified with simple pure Lucene test,
same way as Mike mentioned, performance with NumericDocValue is 10x faster than
retrieving stored field.
Hope

You can also use
You can also use MultiDocValues.getNumericDocValues(reader, field): it
returns a "wrapper" that will do the binary search on every doc

If you are only looking up a small number of hits (e.g. the current
"page" for the user) then typically this cost is fine.
