Go to https://en.wikipedia.org/wiki/Special:ApiSandbox#action=query&list=search and click on "srbackend". There will be three options: * CirrusSearch * CirrusSearch * LuceneSearch I think it should have just two: * CirrusSearch * LuceneSearch
I see only 2 options. What browser are you using?
Firefox 31.0 and Google Chrome 36.0.1985.143.
It is caused by enabling the beta feature "New search" on https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-betafeatures (the problem also disappears if I access the page logged out).
Aha, that's what paraminfo returns: https://en.wikipedia.org/wiki/Special:ApiSandbox#action=paraminfo&format=json&querymodules=search So it's a CirrusSearch problem.
Looks like we just need to get rid of any 'CirrusSearch' entry(ies?) from $wgSearchTypeAlternatives when the BetaFeature is enabled in CirrusSearch\Hooks::initializeForUser.
I can have a look at it in a day or two. If anyone is closer to having the right plugins setup and wants to do it please let me know.
Change 156691 had a related patch set uploaded by Manybubbles: Clean up options with betafeature https://gerrit.wikimedia.org/r/156691
A day or two turned into two weeks but who is counting now that there is a patch.
Change 156691 merged by jenkins-bot: Clean up options with betafeature https://gerrit.wikimedia.org/r/156691
Should be fixed now.
