As Search Service is a part of the SharePoint 2010 services infrastructure, the setup is similar to other services. We have already gone through the setup of other services such as Excel, PerformancePoint, and the managed metadata service.
In this recipe, we will set up an instance of search through Central Administration.
You must have farm-level administrative permissions to the Central Administration site. Set up an Active directory account,
sa_search. This account will be utilized to manage the Search Service.
