powershell - grep string from Message in Get-WinEvent -

i have script check event logs get-winevent, need show complete results of get-winevent output based on search string message column.

is there way grep message column in get-winevent

this current string

get-winevent -computername $target_machine -filterhashtable $params 

you can pipeline output where-object, see example below:

$searchstring="autoconfig"                                                                                                                                                                              get-winevent microsoft-windows-wlan-autoconfig/operational | where-object{$_.message -like "*$searchstring*"}
