I have been presenting how I provision SharePoint 2013 Search for quite a while and have finally gotten around to publishing my script for provisioning a SharePoint Search Service Application with PowerShell. This script can be used to initially provision SharePoint Search in a multi-server environment. With minor tweaks it can also be used to alter an existing topology. There are a couple things that this script demonstrates:

• How to use a configuration file
• How to provision multiple servers from a script
• How to specify where each search component is provisioned
• How to set initial configuration parameters like Crawl Account and Search Center

Feel free to download and try it out. No warranty is expressed or implied!
