Well, if Raxxla was found but not named Raxxla how would anyone know it was Raxxla?
how indeed.. but the idea that eddb would have it because they have most of the named systems doesn't have any connection to raxxla. there is no evidence that raxxla is named ...and plenty of evidence that nothing identifying anything that has been checked out is raxxla (and eddb would contain just things that have been checked out).
if raxxla is in the game, it would not be discoverable from any kind of meta data gleamed from the sources that people have been trying to utilize for years. it's not in the data there. so it's useless for the search for raxxla. about as useless as searching for raxxla in general is.
