Sometimes the producers don't tag the individual vocals used as well.

This was a common reaction back in V2 over Miku Append. Reason being was that many Japanese producers and fans felt she didn't sound like Miku anymore and there was a small backlash over it on Nico videos. So to avoid the reactions that came with the release, many producers didn't say when they used Appends. These days with so many vocaloid getting extended vocal libraries, and added features like XSY, the reaction is not quite the same as it was. But some producers still do not say what vocal they used.

Either way, it doesn't always help to find a vocaloid song. There is often a reason though we don't know for it, be it ignorance on the producers part on that they should to the producer not wanting certain attention.
