After the Ontolica Preview solution has been installed and deployed, the Ontolica Preview feature will be added to the list of farm features and by default it is activated automatically. The site collections features list will contain three Ontolica Preview features, each of which is in fact a separate product. The Ontolica Preview for Search feature adds visual search functionality to Ontolica Search, SharePoint Search, and also to FAST Search for SharePoint. Visual content navigation functionality can be added to Ontolica Aggregate and also to SharePoint document libraries by the Ontolica Preview for Aggregate and Ontolica Preview for Libraries features, respectively. Please make sure your license supports the products you would like to use.
