How can I get all partial matches using Get-ADComputer filter?

I have following PowerShell script

$server = Get-ADComputer -filter {name -like $computerhost}
write-host $server.name

It gives me the ADComputer that contains $computerhost in it's name.

Example: 

$computerhost = linuxserver

matching computer name output: "linuxserver01"

But I actually want the ADComputer if a name of a computer fits inside $computerhost. So if $computerhost is "asdf" I wanna get the computer with the name "a" or "as" or "asd" or "asdf", but not "asda"

Example:

$computerhost = linuxserver (new)

matching computer name output: "linuxserver"

I have no idea how to use wildcards in that way.

If you are looking for partial matches to your string $computerHost filter will not handle that since it does not properly translate to a LDAP query. You would have to process that filter after returning all computers in you selection set. You parameters like -SearchScope to reduce that if you have a large computer base. Simplest approach is to use .contains()

Get-ADComputer -filter * | Where-Object{$computerhost.contains($_.name)}

Need to be careful as .contains() is case sensitive. One thing you could do is force both your string to the same case to remove that issue. 

Where-Object{$computerhost.ToUpper().contains($_.name.toUpper())}

Can also use -match operatore just beware that it supports regex. That should not be an issue here but if your computer names have hyphens they will need to be escaped. 

Where-Object{$_.name -match $computerhost}

Thanks for clarifying via the comments. I think this may be what you're looking for:

Get-ADComputer -filter * | where-object { $computerhost -like "*$($_.name)*" }

For example (i'm using $computers here in place of get-adcomputer):

$computers = 'a','as','asd','asdf','asda'
$computerhost = 'asdf'

$computers | where-object { $computerhost -like "*$_*" }

Returns:

a

as

asd

asdf
