@revi -- we have built this new feature for searching in the help panel, and we want to see how it performs in Korean.
It is enabled on Korean beta labs if you turn on the help panel there: https://ko.wikipedia.beta.wmflabs.org/wiki
When you search in the "Search FAQs" bar, your search will be done only in the Wikipedia namespace -- using the search backend of production Wikipedia (not beta). When you click a link, it will try to open it in beta, which won't work, but you can modify the URL to open it in production Wikipedia.
We're interested in knowing the quality of the results you get when you search for the things that newcomers might search. Could you please try several different searches and record on this task whether you got useful results?
Also please let us know any other feedback or thoughts you have about this feature.
It would be helpful if you can do this by 2019-01-27.
