@D17339 in your code, you specify the list variable name in the template using the

templateName

parameter like this:

renderer.addSearchResults({ templateName: 'mysearch', searchResult: searchResult });

Then, in your template, you will have a list variable that you can iterate over this way:

<#if mysearch?has_content>
    <#list mysearch as result>
        ${result.column1} ...
    </#list>
</#if>
