Export only the machines that meets criteria - powershell

Question

I have a script that works great but I would like to only export the machines that meet one of the three conditions in the foreach statement. Right now it exports all the machines, which I have to clean up manually in excel.
#Create an LDAP searcher object and pass in the DN of the domain we wish to query
$Searcher = New-Object System.DirectoryServices.DirectorySearcher([ADSI]"LDAP://DC=ten,DC=thomsonreuters,DC=com")
#Pass in the ceriteria we are searching for.
#In this case we're looking for computers that are enabled and running Windows 7
$Searcher.Filter = "(&(objectCategory=computer)(objectClass=computer)(!UserAccountControl:1.2.840.113556.1.4.803:=2)(operatingSystem=Windows 7*))"
$Searcher.PageSize = 100000
# Populate General Sheet(1) with information
$results = $Searcher.Findall()
$results | ForEach-Object { $_.GetDirectoryEntry() } |

Answer 1

Try this:
$csv = $csv | where { ($_.CN -notmatch '^U\d{7}') -and ($_.CN -notmatch '\d{3}') -and ($_.extensionattribute7 -match '^U\d{7}$') -and (($_.DistinguishedName -like "*Laptops*") -or ($_.DistinguishedName -like "*Desktops*") -or ($_.DistinguishedName -like "*Virtual*")) }
Before the final line. It should filter out any ones that haven't met any of the criteria in the foreach loop
