but this won't do the trick. So my question is, should I have customized search_parse_file() and search_parse_dir() functions in my config files
Yes, for now. IMHO. Later we can go on with a more generic mkindex.php script. What is important that we don't repeat the same code more than once :)
PS : I also started hacking the XML -> HTML rendering part
Great :)
