Servidor de Pesquisa da Microsoft 2010 Express is an entry-level enterprise search solution that has limited scalability. In Search Server 2010 Express, the topology components of each Search service application must be on one server. Although it is possible to add topology components on that server, in most cases it is not useful. For information about scalable solutions for enterprise search in Produtos do Microsoft SharePoint 2010, see Diagramas técnicos (SharePoint Server 2010).
In Search Server 2010, a crawl database contains data related to the location of content sources, crawl schedules, and other information specific to crawl operations for a specific Search service application. You can distribute the database load by adding crawl databases to different computers that are running SQL Server. Crawl databases are associated with crawl components, and can be dedicated to specific hosts by creating host distribution rules. For more information about crawl components, see Add or remove a crawl component (Search Server 2010). For more information about host distribution rules, see Add or remove a host distribution rule (Search Server 2010).
To add a crawl database to a Search service application
Verify that the user account that is performing this procedure is a member of the Farm Administrators group.
In Central Administration, in the Application Management section, click Manage service applications.
