Basically Federated Search displays search results for additional content that is not crawled by your search server. We can see the data from several sources without indexing them. This is very much helpful when data is stored in external sources, where we do not have control to crawl or index the data. Federated search passes queries to external search engines. And the results are returned from there to the index server.

For example we can show results from Bing or Google in our SharePoint 2010 site.

SharePoint provides an out of box webparts namely Federated results, which is used in SharePoint to show Federated results. In the properties we can defined the Location.

Here is an advantages of federated search in SharePoint according to MSDN.
- You require no additional capacity requirements for the content index, as content is not crawled by SharePoint Enterprise Search.

- You can take advantage of a repository’s existing search engine. For example, you can federate to an Internet search engine to search the Web.

- You can optimize the content repository's search engine for the repository's specific set of content, which might provide better search performance on the content set.

- You can access repositories that are secured against crawls, but which can be accessed by search queries.
