When I try the godmode interface to Omega, it appears to
report the contents of all fields associated with the document.

url=blah blah blah
sample=blah blah blah
caption=blah blah blah
type=text/html

But I don't see a date field. I know omindex is recording one based on
the modification date of the file. How do I know this? Because an Omega
query like query?END=20060405?P=blah will either retrieve or not retrieve
the document based on date.

So if it all works, why do I care what godmode can or cannot see? I care
because the summary results are not displaying the document's date,
and I'd like to enable that feature. I'm pretty sure I see the feature
sitting
in the omegascript for the query interface. I thought godmode
might help me figure out why it doesn't trigger. No such luck. :(

omindex isn't recording a date field; it uses terms for this. We
probably should add a last-modified field.

The following will work, at line 404 in omindex.cc:

    record += "\nlast-modified=" + long_to_string(last_mod);

then use $date{}. However long_to_string() doesn't exist, so here it
is for utils.cc:

string
long_to_string(long val)
{
    CONVERT_TO_STRING("%ld")
}

or something like that. You'll need to add the prototype to utils.h;
this is completely untested :-)
