Hi Steve, I think in the old algo the bytes of the suffix were compared at last, with the patch they are compared before the prefix. Gerd

Hi Gerd
yes, looks much better. I did not test it, but I think it will give a different result for those cases where name contains a suffix (0x1e) . I remember these as lead in/lead out sequences for japanese characters (double byte) characters in ASCII strings?
Japanese almost certainly doesn't work with the global index anyway. I don't see that there would be a difference however - the MultiSortKey is effectively just sorting on the concatenation of the partial and its prefix.
