Since Datafari 3.2 introduces a new , this feature which allows you to save a search. This feature is divided in four parts: 

• The UI: a new div element has been added to the file WebContent/searchView.jsp. The id of this div element is 'save_search' and the div is only added when an authenticated user is detected to prevent unsupported access to the feature.

• The widget: the javascript of the widget that adds the search button and implements its behavior is located in WebContent/js/AjaxFranceLabs/widgets/SaveSearch.widget.js and is instanciated in the file WebContent/js/search.js. The widget javascript file needs also to be imported in the file WebContent/searchView.jsp. The widget function is to save all the parameters of the query performed by Solr, thanks to the manager.store object.

• The servlet: Once the user clicks on the "Save search" button, he needs to enter a name and validate. When the 'Validate' button is pushed, the widgets sends the chosen search name and the search infos (the query performed by Solr) to the servlet "/saveSearch". The servlet retrieve the query parameters, the name entered by the user and the username, and insert everything in the Cassandra database. The servlet java code is located in src/main/java/com/francelabs/datafari/servlets/SaveSearch.java

• The database table: The servlet insert the saved search data into the datatable "search" of the Datafari database of Cassandra. This table is created thanks to the script datafari-cassandra/conf/dev-env/tables and is composed of three fields:

  • username: the user name

  • name: the search name entered by the user

  • request: the Solr query parameters corresponding to the saved search
