[Xapian-discuss] Usage of DateRangeValueProcessor

[Arjen Smedes]

Hi All,

After some ample trying and checking code, I'm stuck again. I can't get the
daterangevalue stuff to work. Here are some snippets of my problem:

1. class PortCallIndexer(Indexer):
    fields = [
        'estimated_date_of_arrival',
    ]

    tags = [
        ('eta', 'estimated_date_of_arrival'),
    ]

    def _get_query_parser(self, *args, **kwargs):

        query_parser = Indexer._get_query_parser(self, *args, **kwargs)
        query_parser.add_valuerangeprocessor(DateValueRangeProcessor(8,
"eta:"))

        return query_parser

2. some delve output:

3. I'd like to use the index to search for date-ranges. For examples, all
entries between 2011/06/01..2011/08/01, but I have tried a number of search
queries, none gives me what I need:

eta:2011/06/01..2011/08/04
eta:2011/06/01

etc, etc.

I'm sure I have missed an important point here, but in case I haven't: I
need help with this. The http://xapian.org/docs/valueranges is not extensive
enough here to help me out.

Thanks in advance.
