[Xapian-discuss] Problems with positions and replace_document

[Fernando Nemec]

Hi Rafael, thanks for your reply.

Here you go. I put my code attached to this message.

By the way, I'm using gcc 4.1.1 on Fedora core 4. The flags I'm using
are on the top of program, as well as the path to the db. Also, I'm
using compiled xapian-core 0.9.6 and flint.

Thanks,

Nemec
