Thread:Project:Support desk/ ask: when there is no value

Hi,

If Wildcards are written as "+" and allow any value for a given condition. For example, born in::+ returns all pages that have any value for the property «born in». What is the wildcard for when there is no value? In the example below I am trying to find the pages where the review date is still blank - what should be where the (?) is in Date for review::

Thanks,

Rich
