View full history for powershell, not just current session

I have this in my PS profile:

function hist { 
  $find = $args; 
  Write-Host "Finding in full history using {`$_ -like `"*$find*`"}"; 
  Get-Content (Get-PSReadlineOption).HistorySavePath | ? {$_ -like "*$find*"} | Get-Unique | more 
}

The solution commented by "charles ross" is what I was looking for:

Get-Content (Get-PSReadlineOption).HistorySavePath | more
