Yeah but if it happens that for a certain document field1 has only one value
and in that case I can't know it is intended as a multiple. in that case
adds.size() would be == 1 and it would look as normal field.
What i need is to mark that field is intended to be multiple no matter if it
contains 1 value or 10.
I need this because my serach results are passed as JSON to other consumers
and i have to tell them what's the structure.
