Before going to configure the sort attributes let’s see How It Works

How It Works (Sorting)

Whether you sort , list or search assets in the ES, Ultimately it is a search(AdvanceSearch, StrictSearch or Search) query which does the work.More specifically a solar query. So let’s go into the code level to see what is happening inside When you select a sort attribute from the sort drop-down menu.

When you click on an item in the sort drop-down menu, it sends an AJAX GET request to <hostname>:<port>/store/assets/<asset_type>/list  endpoint with the selected sorting attribute name and conditions.Following is the sample request URL with URL encoded parameters.



This request is handled by the <ES-HOME>/repository/deployment/server/jaggery apps/store/extensions/assets/default/pages/list.jag . There it unloads the URL encoded parameters and goes through series of filters(ie: Previous sample query goes through !tag !q else !popular else !isGroupingEnabled) to route the request to proper handler.From the list.jag script, It hands over the data coming through the request parameter to method to do the further processing.Inside the it further processes the query and paging parameters and handover those into which is a search method resides in ArtifactManager. In the method, it finally passes the query parameters to the Java API  findGenericArtifacts after making the parameters usable in the solr query.

Ultimate search action is done using solr engine.Following is an extract from solr result JSON which relates to the sorting query sample mentioned above.

The findGenericArtifacts method returns an array of assets which returns from the solr engine, and

Configuring sort attributes

So finally come to the main topic.Configuring the sort attributes.We have written all the above (How It Works) mind-boggling codes to make sure that working with ES is easy and intuitive to its users and developers, So configuration is simple.

Locate the <ES-HOME>/repository/deployment/server/jaggeryapps/store/extensions/assets/default/asset.js file in your distribution.Append a new associative array named sorting to asset.configure object as shown below.

Add the desired sort attribute name(As defined in the asset RXT file) and map a meaningful label to that attribute name. The given label name will appear in the sort drop-down menu.
