Once the diskcache got the files cached, a full mame scan takes less than 7 seconds. And even for indexing you have to read them once (and the scanner accesses the files only once anyway). As long as the name of the set is already correct, it's a direct file access. So there is no need for an index and you got no real benefit from it.
Since you need to reread the files anyway (because something could have been changed), the scanner has to reaccess the sets anyway. The rebuilder is filebased and so an indexing mechanism isn't needed since it works the other way around. It reads a file, matches the hashvalue and recreates the file in the destination.
