[Dbix-class] search syntax for null values in dbix

[jagdish eashwar]

Hi,

I haven't been able to find the exact syntax for searching null values
either in the documentation or on google. I tried :
@myarray = $schema->resultset('model')->search({fieldname => undef})
but it didn't retrieve any row although there are matching rows in the table.
