Filter: show only files starting with given letter? (f*.doc)

(f*.doc) ... this works fine in every other program I’ve used, not sure why it’s different in OP.
It filters all files with the letter anywhere in the name. Like using (f.doc).

Is this an oversight, bug, limitation to capabilities, or just requires an unconventional filter operand method?

Thanks

Turn off Preferences / File Displays / Filter Bar / Partial matching (assuming we're talking about the filter bar).

Ok, you got me, I forgot about a setting. It's getting harder and harder to find a bug anymore!
