Your search might be slow because the index is not running

I have been put in charge of a Windows Server 2012 AWS instance and have no experience dealing with this operating system.

I get a warning when attempting to search using the file explorer which states "Your search might be slow because the index is not running."

I would like to enable search indexing but every tutorial I find using Google is for older versions of Windows Server and have not produced a solution.

On Windows Server 2012 according to https://support.microsoft.com/en-us/kb/

1. Start Server Manager.
2. Click Manage, and then click Add Roles and Features
3. On the Before You Begin page, click
4. On the Installation Type page, select Role-based or Feature-based Installation, and then click
5. On the Server Selection page, select the server or virtual hard disk on which to install Windows Search
6. On the Features page, select Windows Search Service, and then click
7. On the Confirmation page, verify that Windows Search Service is listed, and then click Install.
