remove fields

[Fadzi Ushewokunze]

hi all,

there are 4 document fields in my index that i am not indexing anymore;

then i have 4 new fields i need to add to my index, so i created a new
indexing filter.

how i can add these new fields while preserving the removed fields in
the existing docs?

at the moment when i run bin/index all non-indexed fields get removed
from the index;
