Why has the search service applciation section no similar database configuration options like the other service applications?
<!-- <*DB> below designates the suffix portion of the database name. For example if your DBPrefix (above) was "SharePoint", and the name below was "ServiceApp", your full DB name would be "SharePoint_ServiceApp" -->
<!-- If you are creating an alias (recommended!), <DBServer> is actually the value of the SQL alias; otherwise it's the NetBIOS name of the SQL server or instance.
If you leave <DBServer> blank, the default DBServer value for the farm is used -->
<!-- The script can create a SQL alias for you. Enter the DBInstance, and if you leave <DBPort> blank, script will assume default port value of 1433 -->
