[EP-tech] OAI : need some explanations about custom sets and filters
Hi Laurent,
If I remember correctly, it's an 'AND' in the vanilla oai2 interface.
From: [EPRINTS_ROOT]/cgi/oai2
my $searchexp = $ds->prepare_search(
allow_blank => 1,
filters => [
@{$filters},
],
custom_order => "eprintid",
limit => ($PAGESIZE+1) );
EPrints::DataSet::prepare_search calls EPrints::Search::new - the default setting for a search is 'satisfy_all' = 1.
You could copy the cgi script above into:
[EPRINTS_ROOT]/archives/[ARCHIVEID]/cgi/oai2
and define a key on the oai set config to switch satisfy_all between 1 and 0 as necessary.
I have not tried this. It's a possible solution for what you need - but entirely untested!
If it doesn't work, or you have other questions, let me know!
Cheers,
John
PS You may also be interested in http://bazaar.eprints.org/411/ - which flags anything that has a datestamp, but that is not currently live as 'deleted' in the OAI-PMH interface (which is more compliant with that standard).
The changes may have been merged into the core of EPrints - comparing the cgi/oai2 files should show if this is the case.

Hi there
As we do need to define an OAI custom set into our repository, I'd like to know
if the different filters criteria work only with an implicit "AND" operator
(unfortunately not "OR"), and if exists a negative operator (kind of "!=>")...
Regards
