+	 * <p>
+	 * 	The listing API provides paginated results by using the query parameters limit and offset.<br/>
+	 * 	It returns an array list of string containing the ids (i.e. names) of the items.<br/>
+	 * 	Each name can be used as <code>{ITEM_ID_PARAMETER}</code> path parameter to manage such item.
+	 * </p>
+	 * 
+	 * <h4>Filtering options</h4>
+	 * <p>
+	 * 	The listing method offers options to filter the results, thus enacting to search for items including spatial search (see ext_bbox below).<br/>
+	 * 	It accepts the following query parameters (a subset of Solr search query parameters, see Solr Query Syntax):
+	 * </p>
+	 * 
+	 * <dl>
+	 * 	<dt>q (string)</dt>
+	 * 	<dd>
+	 * 		the solr query. Optional. Default: "*:*" See Solr Query Syntax.
+	 *  	E.g. <code>/items?q=title:foo</code> returns the items with word "foo" in the title;
+	 *  </dd>
+	 * 
+	 *  <dt>fq (string)</dt>
+	 *  <dd>
+	 *  	Filter query. A query string that limits the query results without influencing their scores.
+	 *  	Note: <code>+site_id:{ckan_site_id}</code> is added to this string prior to the query being executed.<br/> 
+	 * 		E.g. <code>/items?q=title:foo&fq=notes:bar</code> returns with word "foo" in the 'title' and the word "bar" in the 'notes';
+	 * 	</dd>
+	 * 
+	 * 	<dt>fq_list (list of strings)</dt>
+	 * 	<dd>
+	 * 		additional filter queries to apply.<br/>
+	 * 		E.g. <code>/items?q=title:foo&fq_list=...</code> returns the items with word "foo" in the 'title'
+	 * 	</dd> 
+	 * 
+	 * 	<dt>sort (string)</dt>
+	 * 	<dd>
+	 * 		sorting of the search results. Optional. Default: 'relevance asc, metadata_modified desc'.
+	 * 		As per the solr documentation, this is a comma-separated string of field names and sort-orderings.<br/>
+	 * 		E.g. <code>/items?q=title:foo&sort=name+asc</code> returns the items with word "foo" in the 'title' 
+	 * 		sorting the results by name ascending;
+	 * 	</dd>
+	 * 
+	 * 	<dt>include_private (bool)</dt>
+	 * 	<dd>
+	 * 		if True, private datasets will be included in the results.
+	 * 		Only private datasets from the user’s organizations will be returned. For the sysadmins will be returned all private datasets. 
+	 * 		Optional, the default is False.<br/>
+	 * 		E.g. <code>/items?include_private=true</code>
+	 * 	</dd>
+	 * 
+	 * 	<dt>ext_bbox</dt>
+	 * 	<dd>
+	 * 		The coordinates of the upper-right and bottom-left angle of a rectangular to query for.
+	 * 		The form is Lat,Long,Lat,Long<br/>
+	 * 		E.g. <code>/items?limit=10&offset=0&q=Pollution&ext_bbox=-7.535093,49.208494,3.890688,57.372349</code> 
+	 * 		returns the first 10 items with 'Pollution' having a spatial coverage in the specified bounding box.
+	 * 	</dd>
+	 * </dl>
+	 * 
+	 * @param limit To get unlimited results the limit query parameters must be set to -1. 
+	 * 	If the results are too much the operation could fail. 
+	 * 	It is recommended to request no more than 1000 results. 
+	 * @param offset The offset parameter indicates the starting position of the result.
+	 * @param count It indicate that the result must contains only the total number of items of the query.
+	 * @return It returns an array list of string containing the ids (i.e. names) of the items.<br/> 
+	 * 	E.g.<pre>["item0","items1",...,"item10"]</pre>
+	 * 	
+	 * 	In the case the query parameter <code>count=true</code> it returns the total number of items of the query.
+	 *  E.g. <pre>{"count":148}</pre>
