object.FindItem (string, value, index, match)

How come that when retrieving a string from a listview, there is no difference when using the match setting value 1 or 0 ??
I've tried searching through a listview with
the match setting constant 'lvwPartial' to look for strings which start for example with
"Micro" - but this doesn't work, even the short example described in the msdn library
which is:

For example, to find the ListItem whose text is "Autoexec.bat", use:

'Create a ListItem variable.
Dim itmX As ListItem
'Set the variable to the found item.
Set itmX = ListView1.FindItem("Auto",,,lvwpartial)
