Xapian discuss - Apr 2006 - Omega example

I've taken the liberty of adding an example Omega config, install and 
indexing to the wiki.  I've added a pointer to the front page.  I had 
hoped I'd be able to actually put an html document on the wiki, but I 
didn't seem to be able to, so I've added a link to the tutorial on my
site.

Perhaps we can shuttle off a number of the "how do I get omega
working"
question off to that example.

Cheers,
Jim.

Yeah, allowing anyone to put arbitrary HTML on your site is allows
cross-site scripting attacks, and parsing HTML to remove "unsafe"
parts
isn't easy to get right.  Also, HTML isn't the easiest markup to learn.

So wikis use their own simple markup language (which varies between
different wiki implementations but they usually have a lot in common).

Anyway, I've converted your HTML to wiki markup while waiting for debian
packages to build (or fail to build more often, sigh):

Generally it looks pretty good.  Suggesting people run the indexer as
root really isn't a good idea though.

Xapian and Omega largely use C++ strings rather than raw buffers which
should help avoid buffer overflows, but several of the filter programs
which omindex calls have had security advisories in the past couple of
years.  Running as root means that the consequences of any security
hole could be a lot more serious.

For now, I've added a note that it's not recommended.  I'll rewrite
that part later if nobody beats me to it.

Cheers,
