Now web visitors don’t need to address diverse databases separately, they can enter query into a single web form and get back arranged results from federation of:

  • diverse web sites and subsites connected with one organization (built on the basis of Plone or other content management system);
  • intranet resources that combine websites, web applications, knowledge and project management systems;
  • website(s) and blog(s) from different domains;

Additional features federated search engine can provide:

  • more specialised search - only relevant and thematic sources are part of federation, users won’t need to welter in huge volumes of information from global search;
  • accessibility - federated search provides even outcomes with restricted access, if you don’t have right to view them, you can ask for owners permission.
