See: http://en.wikipedia.org/w/index.php?title=Special:Search&redirs=1&search=special:&fulltext=Search&ns0=1 http://en.wikipedia.org/w/index.php?title=Special:Search&redirs=1&search=media:&fulltext=Search&ns0=1
Seaching for "special:" give same result as for "1". And results for "media:" and for "2" are same too.
No need redires=1, fulltext=Search, ns0=1 etc. Just followings return returns same result. http://en.wikipedia.org/w/index.php?title=Special:Search&search=special: http://en.wikipedia.org/w/index.php?title=Special:Search&search=media:
Additionally: This bug seems to come only on 1.17wmf1. Following wikis which uses other version return different. * The Documentation Foundation Wiki (1.16.0) http://wiki.documentfoundation.org/index.php?title=Special:Search&search=special: * translatewiki.net (1.18alpha) http://translatewiki.net/w/i.php?title=Special:Search&search=special:
There are similar examples. http://en.wikipedia.org/w/index.php?title=Special:Search&redirs=1&search=:&fulltext=Search&ns0=1
Wikimedia wikis are using Lucene Search. Looks like a problem with that search engine, not with the mediawiki search engine.

Still weird in Cirrus. Will revisit.
Actually this is all working as intended, I see no bug here. Closing INVALID.
