Extending Assets Search extending-assets-search
You can extend Adobe Experience Manager Assets search capabilities. Out of the box, Experience Manager Assets searches for assets by strings.
Searching is done via the QueryBuilder interface so the search can be customized with several predicates. You can overlay the default set of predicates in the following directory: /apps/dam/content/search/searchpanel/facets
.
You can also add additional tabs to the Experience Manager Assets admin panel.
Overlaying overlaying
To overlay the preconfigured predicates, copy the facets
node from /libs/dam/content/search/searchpanel
to /apps/dam/content/search/searchpanel/
or specify another facetURL
property in the searchpanel configuration (the default is to /libs/dam/content/search/searchpanel/facets.overlay.infinity.json
).
apps
does not exist and needs to be created. Ensure that the node types match those under / libs
.Adding tabs adding-tabs
You can add additional Search tabs by configuring them in the Experience Manager Assets Admin. To create additional tabs:
-
Create the folder structure
/apps/wcm/core/content/damadmin/tabs,
if it does not already exist, and copy thetabs
node from/libs/wcm/core/content/damadmin
and paste it. -
Create and configure the second tab, as desired.
note note NOTE When you create a second siteadminsearchpanel, be sure to set an id
property in order to prevent form conflicts.
Creating Custom Predicates creating-custom-predicates
Experience Manager Assets comes with a set of predefined predicates that can be used to customize an Asset Share page. Customizing an Asset Share in this way is covered in Creating and Configuring an Asset Share Page.
In addition to using pre-existing predicates, Experience Manager developers can also create their own predicates using the Query Builder API.
Creating custom predicates requires basic knowledge about the Widgets framework.
The best practice is to copy an existing predicate and adjust it. Sample predicates are located in /libs/cq/search/components/predicates
.
Example: Build a simple property predicate example-build-a-simple-property-predicate
To build a property predicate:
-
Create a component folder in your projects directory, for example
/apps/geometrixx/components/titlepredicate
. -
Add
content.xml
:code language-xml <?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="https://sling.apache.org/jcr/sling/1.0" xmlns:cq="https://www.day.com/jcr/cq/1.0" xmlns:jcr="https://www.jcp.org/jcr/1.0" jcr:primaryType="cq:Component" jcr:title="Title Predicate" sling:resourceSuperType="foundation/components/parbase" allowedParents="[*/parsys]" componentGroup="Search"/>
-
Add
titlepredicate.jsp
.code language-xml <%-- Sample title predicate component --%><%@ page import="java.util.Calendar" %><% %><%@include file="/libs/foundation/global.jsp"%><% // A unique id is necessary in case this predicate is inserted multiple times on the same page String elemId = "cq-predicate-" + Long.toString(Calendar.getInstance().getTimeInMillis()); %><div class="predicatebox"> <div class="title">Title</div> <%-- The wrapper for the form elements. All items will be append to this wrapper. --%> <div id="<%= elemId %>" class="content"></div> </div><script type="text/javascript"> CQ.Ext.onLoad(function() { var predicateName = "property"; var propertyName = "jcr:content/metadata/dc:title"; var elemId = "<%= elemId %>"; // Get the page wide available QueryBuilder. var qb = CQ.search.Util.getQueryBuilder(); // createId adds a counter to the predicate name - useful in case this predicate // is inserted multiple times on the same page. var id = qb.createId(predicateName); // Hidden field that defines the property to search for; in our case this // is the "dc:title" metadata. The name "property" (or "1_property", "2_property" etc.) // indicates the server to use the property predicate // (com.day.cq.search.eval.JcrPropertyPredicateEvaluator). qb.addField({ "xtype": "hidden", "renderTo": elemId, "name": id, "value": propertyName }); // The visible text field. The name has to be like the one of the hidden field above // plus the ".value" suffix. qb.addField({ "xtype": "textfield", "renderTo": elemId, "name": id + ".value" }); // Depending on the predicate additional parameters allow to configure the // predicate. Here we add an operation parameter to create a "like" query. // Again note the name set to the id and a suffix. qb.addField({ "xtype": "hidden", "renderTo": elemId, "name": id + ".operation", "value": "like" }); }); </script>
-
To make the component available, you need to be able to edit it. To make a component editable, in CRXDE, add a node
cq:editConfig
of primary typecq:EditConfig
. So that you can remove paragraphs, add a multi-value propertycq:actions
with a single value of DELETE. -
Navigate to your browser, and on your sample page (for example,
press.html
) switch to design mode and enable your new component for the predicate paragraph system (for example, left). -
In Edit mode, the new component is now available in the sidekick (found in the Search group). Insert the component in the Predicates column and type a search word, for example, Diamond and click the magnifying glass to start the search.
note note NOTE When searching, be sure to type in the term exactly, including the correct case.
Example: Build a simple group predicate example-build-a-simple-group-predicate
To build a group predicate:
-
Create a component folder in your projects directory, for example
/apps/geometrixx/components/picspredicate
. -
Add
content.xml
:code language-xml <?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="https://sling.apache.org/jcr/sling/1.0" xmlns:cq="https://www.day.com/jcr/cq/1.0" xmlns:jcr="https://www.jcp.org/jcr/1.0" jcr:primaryType="cq:Component" jcr:title="Image Formats" sling:resourceSuperType="foundation/components/parbase" allowedParents="[*/parsys]" componentGroup="Search"/>

Customizing Search Results customizing-search-results
The presentation of search results on an Asset Share page is governed by the selected lens. Experience Manager Assets comes with a set of predefined lenses that can be used to customize an Asset Share page. Customizing an Asset Share in this way is covered in Creating and Configuring an Asset Share Page.
In addition to using pre-existing lenses, Experience Manager developers can also create their own lenses.
