[Xapian-discuss] sort by value fails

[Dr.BYTE at web.de]

thank you for your reply. if i see correctly, i will have to write a serializer method which converts è to e and Ö to Oe and so far.
is it possible, that sort by value cannot sort floats correctly, too? i never workt with C, so i dont know how memcmp compares floats.

regards,
sven
