search feature failing with two or more organisations in 'ckan_organizations' filter

Created by: mkazmiers

We're currently testing the latest build (#59). An error occurs when setting two or more organisations in the 'ckan_organizations' filter. An example here :

var config = {
ckan_api: 'https://trouver.datasud.fr/',
ckan_organizations: ['communaute-dagglomeration-ventoux-comtat-venaissin','commune-de-carpentras'],
          // ckan_groups: ['group1'],
          // ckan_tags: ['tag1'],
          // ckan_facets: {
          //    res_format: 'HTML',
          //    datatype: 'type'
          // },
		  facet_display: ['organization'],
		  data_sort: 'title_string asc',
		  result_page_size: 25,
		  thumbnails_display: true,
		  display_header: true,
		  display_sidebar: true
      }

When researching 'wi-fi' in the top search bar, results are obtained from non-expected organisations (e.g 'ville-marseille' and 'ville-digne-les-bains'), as if filters are forgotten in the search.

This doesn't occur when a single organisation is set, for instance 'commune-de-carpentras'. We get only the result from the one organisation. Same behavior is expected with two or more :-)
