http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&fulltext=Search&ns0=1&redirs=1&search=intitle: (append one UTF-8 character) does not show redirects if the character searched has code point above U+007F. en.wikipedia.org/wiki/Special:Search/intitle: even does not show articles (non-redirect pages) for some code points. Apparently the bulk of this bug affects only en.wiki. Examples: http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%C2%85&fulltext=Search&ns0=1&redirs=1&profile=advanced – but U+0085 NEL (non-graphic) redirect exists: http://en.wikipedia.org/wiki/%C2%85 http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%C2%A2&fulltext=Search&ns0=1&redirs=1&profile=advanced – but the [[¢]] redirect exists: http://en.wikipedia.org/wiki/%C2%A2 Note: I was unable to locate any wiki where intitle:¢ for U+00A2 gives some results, which means that in other wikis something is broken too http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%CF%B7&fulltext=Search&ns0=1&redirs=1&profile=advanced – but the [[Ϸ]] redirect exists: http://en.wikipedia.org/wiki/%CF%B7 http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%D0%81&fulltext=Search&ns0=1&redirs=1&profile=advanced Note it works in another language: http://ru.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%D0%81&fulltext=Search&ns0=1&redirs=1&profile=advanced&uselang=en http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%D0%86&fulltext=Search&ns0=1&redirs=1&profile=advance Note it works in another language: http://uk.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%D0%86&fulltext=Search&ns0=1&redirs=1&profile=advanced&uselang=en http://en.wikipedia.org/wiki/Special:Search/intitle:%E8%A5%BF – but the [[西湖]] dab page exists: http://en.wikipedia.org/wiki/%E8%A5%BF%E6%B9%96 Note it works in another language: http://zh.wikipedia.org/wiki/Special:Search/intitle:%E8%A5%BF
I am not sure that understand correctly what the combination of search=intitle: which redirs=1 has to do, but along the example with "西" there are numerous non-searchable characters even directly in the title of article, and not restricted only to en.wikipedia. http://en.wikipedia.org/wiki/Special:Search/intitle:%E2%80%93 – though a huge number of articles with en dash exist in en.wikipedia http://ru.wikipedia.org/wiki/Special:Search/intitle:%E2%80%94 – though a huge number of articles with em dash exist in ru.wikipedia http://ru.wikipedia.org/wiki/Special:Search/intitle:%C2%AB – though a huge number of articles with guillemets exist in ru.wikipedia http://ca.wikipedia.org/wiki/Especial:Cerca/intitle:%C2%B7 – though a large number of articles with interpunct exist in ca.wikipedia
Problem is still valid.
We're in the process of migrating over from Lucene to CirrusSearch, so I'm marking this bug as RESOLVED WONTFIX. That said, this bug still seems to exist in CirrusSearch. I've filed an equivalent bug in MediaWiki extensions -> CirrusSearch. Check the See Also on this bug for more information.
