I has a field “ISInternalDeadlineAll” which is multiple date value. I try to search [ISInternalDeadlineAll] >= 28/01/2008, the document contains multiple value cannot find. e.g.

ISInternalDeadlineAll

28/01/2008 00:00:00 ZE8

28/01/2008 00:00:00 ZE8

01/02/2008 00:00:00 ZE8

But if the ISInternalDeadlineAll contains single value “28/01/2008 00:00:00 ZE8”, the document can find.

How can search a document with mutliple date value?
