Continue script, once search will be done - powershell

Question

I have command in the script to do compliance search(Microsoft Exchange) and it takes ~20 minutes and I need to wait until it will be done to use powershell. I need to continue script automatically, once search will be done. Here is example:
ShowSearchResults
Write-Host "You can find search results under the following path: C:\ExportResults" -ForegroundColor Green
Write-Host "Do you want to delete found mails? (y/n)" -ForegroundColor Green
New-ComplianceSearchAction -SearchName $FinalSearchName -PurgeType softdelete -Purge
And when I start "ShowSearchResults" I need to wait once it will be done. I need to show "Write-Host..." once search will be done, until it, I need my session.
I tried with Start-Job, but I didn't find the solution with this way

Answer 1

Your code seems good to me except for 1 misrepresented statement.
PowerShell, like most scripting languages, will execute the commands/statements in your script from top to bottom by default.
So your Write-Host will be executed only after the previous command is completed.
As for the "misrepresented" statement, you might've wanted to use Read-Host to get a user choice to soft delete your last search. So after small corrections, your code looks like the below,
#1
$ComplianceSearchJob = Start-Job -ScriptBlock {
ShowSearchResults
Write-Host "You can find search results under the following path: C:\ExportResults" -ForegroundColor Green
# Invoke-Item "C:\ExportResults\SearchResults.csv"
}
#2
Receive-Job $ComplianceSearchJob -Keep
#3
$DeleteChoice = Read-Host "Do you want to delete found mails? (y/n): " -ForegroundColor Green
if($DeleteChoice -eq "Y"){ # case insensitive
New-ComplianceSearchAction -SearchName $FinalSearchName -PurgeType softdelete -Purge
}
EDIT 1: Added Invoke-Item to open the C:\ExportResults\SearchResults.csv file in a comment.
EDIT 2: Used Start-Job to allow running as a background process.
