Date Search

Hi,

I am performing a search:search query on an date element (which has a element date range index set).
In the database some times the element date will have null value.
When doing a search for a given date eq, gt or lt we are getting the documents as per search criteria but also getting the documents where the date element is blank.
Please advise.

Thanks,
Rushabh Mehta
