NEST: Avoid storing default values false, 0 etc

That is exactly what I want to archive.
I am aware of the side effects and it should be used with caution.
I do only want to filter on positive int or true, no sorting.
Unset or false/0 could be found with the negated query, not true or not postive, if that is desired, right?

Will the JsonNetSerializer work with the mapping done in Nest or do I have to redo mapping for JsonNet?
