How to handle filter query against empty fields

Hi all,

I have a field(s) in a schema which I need to be able to specify in a
filter query. The field is not mandatory, therefore it can be empty. I
need to be able to run a query with a filer : " return only docs which
does not have value for the field " ...

What would be the optimal recommended way of doing this with Solr?

Thanks!

Best,
Jozef

There are two approaches for this. Please read my earlier post :
