* <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>
|
||
* <em>Optional</em>.<em>Default:"*:*"</em><br/>
|
||
* The solr query. see Solr Query Syntax<br/>
|
||
* E.g. <code>/items?q=title:foo</code> returns the items with word "foo" in the title.<br/>
|
||
* E.g. <code>/items?q=extras_systemtype:MyProfile</code> returns the items having the profile <em>MyProfile</em>
|
||
* </dd>
|
||
*
|
||
* <dt>fq (string)</dt>
|
||
* <dd>
|
||
* <em>Optional</em>.<em>Default:null</em>.<br/>
|
||
* Filter query. A query string that limits the query results without influencing their scores.<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>
|
||
* <em>Optional</em>.<em>Default:null</em>.<br/>
|
||
* 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>
|
||
* <em>Optional</em>.<em>Default:"relevance asc, metadata_modified desc"</em>.<br/>
|
||
* Sorting of the search results.<br/>
|
||
* 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>
|
||
* <em>Optional</em>.<em>Default:false</em>.<br/>
|
||
* If True, private datasets will be included in the results.<br/>
|
||
* 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>
|
||
* <em>Optional</em>.<em>Default:null</em>.<br/>
|
||
* The coordinates of the upper-right and bottom-left angle of a rectangular to query for.
|
||
* The form is <code>Lat,Long,Lat,Long</code><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>
|
||
*
|
||
* <dt>own_only (bool)</dt>
|
||
* <dd>
|
||
* <em>Optional</em>.<em>Default:false</em>.<br/>
|
||
* If True, only the items of the requester user will be included in the result.<br/>
|

* E.g. <code>/items?limit=10&offset=0&own_only=true>
|
||
* </dd>
|
||
*
|
||
* <dt>all_fields</dt>
|

* <dd>
|
||
* <em>Optional</em>.<em>Default:false</em>.
|

* @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.
|
||
* 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>
