I think, you read it wrong:
It would "Whatever" show if the filter is "equals Whatever"!
If you use equals, it is case sensitive and needs a 100% match.
If you use contains, parts are ok.
For example four romfiles on your harddrive:
Twisted Metal.aaa
Twisted Metal (USA).aaa
Twisted Metal - Whatelse.aaa
Twisted Sisters.aaa
Name equals Twisted Metal
Output :
Twisted Metal
Name contains Twisted Metal
Output:
Twisted Metal.aaa
Twisted Metal (USA).aaa
Twisted Metal - Whatelse.aaa
Name equals Twisted
Output:
empty/nothing shown
Name contains Twisted
Output:
Twisted Metal
Twisted Metal (USA)
Twisted Metal - Whatelse
Twisted Sisters
