search for: actual_date_of_arrival

Hi, I have been playing with Djapian recently, and am running into a problem where I have the following setup: class SomeIndexer(Indexer): fields = [ 'actual_date_of_arrival', ] tags = [ ('ata', 'actual_date_of_arrival'), ] Some model instances exist with dates like 2011/07/04 and 2011/07/04 and my search should yield all model instances within the range 2011/07/04..2011/07/08, but the search I am running: ata:(2011/07/04..201...
