The size of each farm is based on the number of items that are crawled and included in the search index. Architecture requirements can vary depending on the composition of the data that is crawled (size of items and formats). The examples illustrate the type of search components needed and how many of each. Use these examples as starting points for planning your own search environments. For more information about search processes and how search components interact, see Search Architectures for SharePoint® Server 2013 (http://go.microsoft.com/fwlink/p/?LinkId=258643).
