Allahbaksh,
I don't think, Lucene could filter out Null and Not null values.
In case if the field value is Null, index the field with value <<NULL>>. To
find all the documents which the field is not null, Search the field, which
does not contain the value <<NULL>>.
Regards
Ganesh

Hi,
What is the optimum way in which I can find all the document which has
