processing for search orders that bear little relationship to
alphabetical order.  As Markus pointed out, most of that overhead is
removed from processing by the use of special 'search' collations.

I think one problem is disbelief in the existence of enough
sophisticated users to matter.  I gather it can be quite hard to obtain
a Swedish interface for editing Thai.
