[~jpountz] Thank you for the reply. I am not at-all familiar with the file 
formats. Can you suggest some blog/article or some class names where I can 
learn more about the different file formats ?

> We have been using doc values to handle soft deletes until now, but this is a 
> bit of a hack as it:
>  - forces users to reserve a field name for doc values
>  - generally doesn't read directly from doc values, instead docs values help 
> populate bitsets and then reads are performed via these bitsets
> It would also be more natural to have both hard and soft deletes handled by 
> the same file format?
