Federated search: one query, multiple databases

Federated search engine is an information retrieval technology that allows a user with only one search query to receive combined results from multiple information resources participating in the federation. Users can view all search results in a single integrated list.
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.

The main means Quintagroup uses to conduct federated search are:

  • Web crawler for web indexing of resources that take part in federation;
  • Sitemaps protocol to collect index files.

I have used a Plone site environment hosted by Quintagroup to develop a workflow application for my business. Since January 2010 ... I have been a customer of Quintagroup and I am very happy about the good and reliable service, including update of the website to version 4.1 of Plone.

...I was a very satisfied customer for 7 years. They made sure that my website was always up, even during a couple episodes of being "slashdotted", and fixed the very few problems that I had in record time. This is a very professionally run outfit...
