Command line support for "bagless" Solr indexes

[phochste]

Using the Perl API of Catmandu one can access data in a Solr installation that doesn't have the notion of 'bags':

  my $store = Catmandu->store('Solr');
  $store->bag->searcher(query => 'any solr query')->each(sub {
  });

This is probably a bug that the bag doesn't have any effect in this code. But it is also a very nice feature to be able to support "bagless" Solr installations.

However, with the command line tools the "bag" is enforced in the Solr query on line 33: https://github.com/LibreCat/Catmandu-Solr/blob/master/lib/Catmandu/Store/Solr/Bag.pm#L33

This gives no results in "bagless" installations

  $ catmandu export Solr to YAML

Can searcher keep the support for bagless queries. Can this support also be added to the generator?

On my system the Searcher actually does use the bag as a filter (fq=_bag:data). Maybe your installation of Catmandu::Solr should be updated?

It's strange that the export command actually uses this searcher instead of Catmandu::Importer::Solr?

As for the "bagless" support:

• how should one differentiate between "use bag data when not provided" and "use no bag at all":

  #these are the same now
  my $bag1 = Catmandu->store("Solr")->bag("data");
  my $bag2 = Catmandu->store("Solr")->bag();

• a configuration option like "bagless: true" should be able to change that, but your query above would show the old answer
