So it sounds to me like this is working as intended. If you want (for example) accented and non accented versions of a letter to sort adjacently, you might want to consider transforming the values so that they sort in the desired order. Cheers, Olly
thank you for your reply. if i see correctly, i will have to write a serializer method which converts ? to e and ? 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 Olly Betts <olly at survex.com> schrieb am 11.09.2008 15:28:15:> On Tue, Sep 09, 2008 at 05:54:17PM +0200, Dr.BYTE at web.de wrote: > > i want use sort_by_value to sort by "username". > > so in the indexing process i add the value i want sort by as value > > > > (lang is php) > > > > $document->add_value(0, 'value'); > > > > when i sort i got all specialchars at the beginning > > Sort by value uses a simple byte-value comparison (like the C function > memcmp()) - it doesn't implement any sort of language-specific collating > orders.

thank you! can you give me some hints where these code parts are located? i tried to find it via the code browser (http://trac.xapian.org/browser/trunk/search-xapian/Xapian) but i didn't find it yet.
