Issue

  • The ModelDocumentContributor interface is used by many entities in Liferay to customize index and search operations.
  • Can it be used to customize indexing and search for journal articles (web contents)?

Environment

  • Liferay DXP 7.2, 7.3, 7.4

Resolution

  • Up until DXP 7.3, Journal entities do not use ModelDocumentContributor.
  • As an alternative you can use an Indexer Post Processor with the method 
    public void postProcessDocument(Document document, Object obj)
  • Examples can be found here and a blade sample can be executed with blade samples indexer-post-processor.
  • In DXP 7.4 Update 15 is already possible to use ModelDocumentContributor. See for example this class.
