Do you have your site fully indexed? It should affect the
group=parameter, but if you are trying to do text/data/link, etc,
indexing is essential.

Possible, but not necessarily. I got the recent server errors online
because something in my online configuration setup triggered a php bug
that was not triggered offline. Nothing to do with apache--though it
did a lousy job reporting the error. And even then windows and linux
work differently in certain situations, so it could be anything. If it
was a missing library, I would think you would get a message in your
php error log for calling an undefined function. Have you checked your
error logs?

This is very strange. The critical lines in the rssfeed function are these:
$pages = BOLTsort(BOLTsearchPageList($args, $zone), $args); // add
third false for no auth checking
if ($_GET['action'] == 'rsslist') return BOLTdisplay($pages, $args);
You'll notice the action=rsslist option uses the exact same array of
pages used later by the script to generate the rss feed. So unless
somehow one or the other cancels out some pages for some reason, their
output should be the same... I'm not denying it, just seems strange.
Both start with exactly the same list of pages at least.

Yes, that could be a bit tricky. :) You could possibly try creating
a custom edit action like this: copy action.edit => action.rss.edit,
and add to the end of the form
[session nextpage {p}&action=source]
That way you should be able to check that what you saved is there now,
and get any messages you need. If it works, we could possibly add it
to the backup file.

This is true, but we could add that functionality perhaps. And in
fact this could be our problem... This line in rss.php ~32 should be
changed from
$pages = BOLTsort(BOLTsearchPageList($args, $zone), $args); // add
third false for no auth checking
to
$pages = BOLTsearchPageList($args, $zone); // add third false for no
auth checking
The way it was written, with the new changes to the core search
function, the sort function gets called twice.
To try adding the other search criteria we need to replace that line
with this entire snippet (let me know if it works--we could polish
this up more nicely, and I'll update the script):
global $outarray
$outarray = BOLTsearchPageList($args, $zone); // add third false for
no auth checking
if (isset($args['text'])) BOLTcheckNest1($args['text'], 'text', $args);
if (isset($args['data'])) BOLTcheckNest1($args['data'], 'data', $args);
if (isset($args['link'])) BOLTcheckNest1($args['link'], 'link', $args);
$pages = $outarray;
This would be cool because you could generate a rss feed of all the
pages that link to a page. IE, put /*[[rss]]*/ on a page and instantly
it gets added to your feed (with link=rss).

Let's see if we can't fix the code before we fix the docs. :)

It should not do this anyway. And it just did it for me! We have some
weird things going on here, Markus... I'm very busy this week, but
I'll stick with you as best I can and try to work through it with you.
Another problem. I tried installing rss in a new field, didn't get it
to work, then uninstalled. Got a white screen. Traced it down to a
couple lines in engine.php that need to be rewritten:
~1428 or so.
elseif ($pageArray[0] == 'rss') {
if (! isset($_GET['action']) &&
BOLTexists('code.skin.rss')) $skin
= 'code.skin.rss';
else $skin = BOLTgetlink($BOLTcodePages, 'skin');
}
This will return the normal skin if code.skin.rss doesn't exist rather
than a whole new skin. Seems the overall logic of this little code
section (lines before and after) could be simplified, but this will
work for now... Does anyone remember why we have a print=true option
here?

You should be able to do sort=lastmodified in the rssfeed function.
Did that not work for you?

Sorry it's not working as well as we'd like. We'll get there. It would
be a fun problem to track down if I had more time today!!!
