Description Hannes 2008-01-30 09:04:10 UTC
On my Mediawiki install using the Search form (either "Go" or "Search") fails.
Instead of a search result I get a 
"No such special page
You have requested an invalid special page."
If I enter I do get to the search page and can do the search.
Also, if I change the URL from "" to "/wiki/Special:Search?foo=bar&search=foo&fulltext=Search" then I get results. If the first GET variable is "search" then the URL fails.

This lead me to believe that my Short URL's might be configured wrongly. I use Lighttpd with the following rewrite-rules (picked from the Manual:Short URL page:
url.rewrite-once = (
        "(^/wiki/[^:]*[\./].*)" => "$1",
        "^/wiki/([^?]*)(?:\?(.*))?" => "/w/index.php?title=$1$2",
        "^/wiki/" => "/w/index.php",

The wiki is installed to directory "w".

Sounds like some problem with your rewrite rules, yes.
Comment 2 Brion Vibber 2008-03-19 00:24:22 UTC
It's somewhat undecided whether we want to support this sort of configuration... some would prefer to more aggressively put parameters after $wgArticlePath/$wgActionPaths-style links.

I'm not very familiar with Lighttpd, but if I see it right, you make a mistake in your second rewrite rule. You add the query string (the part after the '?' char) to the title, but this will rewrite to (using your example) /w/index.php?title=Special:Searchsearch=foo&fulltext=Search
Clearly, you want to add an ampersand between $1 and $2, but that would also add an unnecessary ampersand if you have an empty query string. I would simply add an extra rule so that you have one for queries WITH query string and one for queries WITHOUT query string.

With Apache's mod_rewrite, I can simply use the qsappend flag to copy the query string over automatically. Doesn't Lighttpd have something similar? In mod_rewrite, this flag will even figure out if it has to use ? or & before the query string.
