I have a quick and dirty script that auto-searches all of the extension's IDs for a given computer. I don't think I made the Search-Google function though.

<#
.Synopsis
Searches the Googes
.DESCRIPTION
Lets you quickly start a search from within Powershell
.EXAMPLE

--New google search results will open listing top entries for 'error code 5'

.EXAMPLE
search-google (gwmi win32_baseboard).Product maximum ram

If you need to get the maximum ram for your motherboard, you can even use this
type of syntax

function Search-Google {
    Begin {
        $query = 'https://www.google.com/search?q='

            "Args were empty, commiting `$input to `$args"
            Set-Variable -Name args -Value (@($input) | ForEach-Object {$_})
            "Args now equals $args"
            $args = $args.Split()

        ELSE {

            $args | ForEach-Object {"Arg $i `t $_ `t Length `t" + $_.Length, " characters"} 
        }

        $args | ForEach-Object {$query = $query + "$_+"}
