PS > Get-Help Select-String -Parameter InputObject
 
-InputObject <System.Management.Automation.PSObject>
    Specifies the text to be searched. Enter a variable that contains the text, or type a command or expression that gets the text.
    
    Using the InputObject parameter isn't the same as sending strings down the pipeline to `Select-String`.
    
    When you pipe more than one string to the `Select-String` cmdlet, it searches for the specified text in each string and returns each string that contains the search text.
    
    When you use the InputObject parameter to submit a collection of strings, `Select-String` treats the collection as a single combined string. `Select-String` returns the strings as a unit if it finds the search text in any string. FileInfo objects are treated as a path to a file. When file paths are specified, `Select-String` searches the contents of the file, not the `ToString()` representation of the object.
    
    Required?                    true
    Position?                    named
    Default value                None
    Accept pipeline input?       True (ByValue)
    Aliases                      none
    Accept wildcard characters?  false
