If you have .Net 4.5 installed you can use System.IO.Compression.FileSystem library to create a function which will open and traverse contents of your zip files

$searchTerms = @( "test","bingo","false","one two","england")
function openZip($zipFile){
    try{
        [Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression.FileSystem" ) | Out-Null;
        $zipContens = [System.IO.Compression.ZipFile]::OpenRead($zipFile);  
        $zipContens.Entries | % {
            foreach($searchTerm in $searchTerms){
                if ($_.Name -imatch $searchTerm){
                    Write-Output ($_.Name + "," + $_.FullName + "," + $_.CompressedLength + "," + $_.LastWriteTime + "," + $_.Length);
                }
            }               
        }
    }
    catch{
        Write-Output ("There was an error:" + $_.Exception.Message);
    }
}  

You can then run something like this to obtain filename,full path within zip, compressed size etc.

Get-ChildItem -Path -$filePath *.zip -Recurse -ErrorAction SilentlyContinue | %  {
    openZip $_.FullName  >> c:\path\to\report.csv
    }

You cannot scan the contents of a zip file, since it is compressed and will just come out as garbage. You would have to unzip the file and then search through it.

Follow these instructions: http://www.howtogeek.com/tips/how-to-extract-zip-files-using-powershell/

Copy it down locally and then search for it there, then delete the copies, repeat.
