Since Get-Help accepts wild cards, you can easily list all white papers available for a specific topic. Use this to get you all topics that deal with operators:
Get-Help about_*operator*
You should have a look at this if you want to open all of these Help files and create your own Help file:
Get-Help about_*operator* | Get-Help | Out-File $home\myhelp.txt
& "$home\myhelp.txt"
& "$home\myhelp.txt"
Likewise, if you need to know more about advanced topics, such as remoting, try this:
Get-Help about_*remot*
