Federated Content Search (FCS) is a free service provided by CLARIN that allows researchers to search for specific patterns in datasets from the overall CLARIN resources. The search engine connects to local datasets that are available in the centers, but the data itself remains in the center where it is hosted.

To enable reserachers to search for specific patterns across collections of data, CLARIN offers a search engine that connects to the local data collections that are available in the centres. The data itself stays at the centre where it is hosted – therefore the underlying technique is called federated content search. The search engine summarizes and displays what is available. An easy next step is to go to the centre’s specialised search interface to perform a more sophisticated query.
