Using Find Similar, the Prefix Display / Same / Yes and Prefix Display / Different / Yes options do not find any items.
Prefix Display / Different / Yes and Different / No work correctly, so there is a workaround.
I also did a quick check of the other Yes/No options.
Display Name exhibits the same bug.
HOWEVER, Locked works fine. Perhaps a type-conversion bug?
