I am using the version 12.6.1-1 of the Hippo CMS Enterprise Edition. I am trying to build an advanced search filter which would search articles by a specific category to which the article belongs.
All the examples that I if found online were searching for direct properties of a Document (ex: title, author, body … etc.) and not for the child properties (which are a different document type contributed on a document).
Is there any what to achieve the above?
