We will try to make things as generic as possible, to be able to use as well other search providers, we extend the ExtSearchResultModel Class with the FacettedSearchResultModel FacetedSearchResultModel Class which will only contain the specific getters/setters for faceting.

How do we push the categories to the index ?

Two things have to be distinguished here, content from the website and assets like documents, movies and other stuff.

Content from the website is already picked up by the Heritrix crawler that calls the provider instance through the Extended Search configuration and pushes urls to the solr server which will extract all content and index it.

To add categorization tags, we can add categories to a meta field in the page by adding a script in the HtmlHeader template as follows.

[#assign categories = pageModel.categories!]
[#assign hasCategories = categories?has_content]

[#function getCats itemlist]
    [#-- Assigns: Get Content from List Item--]
    [#local cats = ""]
    [#list itemlist as item]
       [#local itemName = item.@name]
       [#local itemDisplayName = item.displayName!itemName]
       [#local cats = itemDisplayName + "," + cats]
    [/#list]
    [#return cats]
[/#function]


[#if hasCategories]
<meta name="categories" content="${getCats(categories)}"/>
[/#if]
