Hi,

is it possible to set document field as a mandatory? So something like  
opposite of "null\_value" mapping. If the document does not have that field  
or it is null, do not index it and fire error.  
I think this can be useful integrity constrain.

Regards,  
Lukas

No, there isn't an option to do so.
