Searching with prefix doesn't work on ca.wiki:
https://ca.wikipedia.org/wiki/Special:Search?search=Foo&prefix=List&fulltext=Search
searches for "Foo" in all pages instead of "Foo prefix:List". Checked also in test.wikidata.org, both projects with extension CirrusSearch. This affects the behaviour of inputbox with parameter prefix, widely used for searching in archives, i.e. the local Village Pump https://ca.wikipedia.org/wiki/Viquip%C3%A8dia:La_taverna
Version: unspecified
Severity: normal
As a short term solution I have recommeded vriullop to use the parameter "&srbackend=LuceneSearch"as a way to retrieve the results from MWsearch, which is still installed in ca.wikipedia.org.

I have learned this parameter from Chad since I couldn't find it documented. <collateral comment>In general I'm missing a page for CirrusSearch user documentation. Does it exist?</collateral comment>
<collateral response>https://www.mediawiki.org/wiki/Search/CirrusSearchFeatures is a start</collateral response>
Oh, sorry. My advice to vriullop won't work. The search he is referring to is done using [[mw:Extension:InputBox]] and therefore the parameters can't be modified by editors.
It looks like I implemented something totally different when I build the prefix: filter. I'm fixing this to work just like the documentation on https://en.wikipedia.org/wiki/Help:Searching
Change 88209 had a related patch set uploaded by Manybubbles:
Replace prefix: implementation.
Change 88210 had a related patch set uploaded by Manybubbles:
Tests for proper prefix: implementation.
Ouch, sorry, I hadn't reported it because I couldn't find what was the exact syntax for prefix: in Cirrus so I thought I maybe was just using the wrong one.
With Lucene, it was important to 1) not to use underscore or anything in the title, but just quote it literally, 2) not have a space between "prefix:" and the title. Is this reimplementation like that or more flexible?
