Advanced search does not work on huwiki for unknown reasons.

Using the advances parameters on hu.wikipedia.org one always gets no results. The advanced search parameters are not mapped to searchkeywords in the search-URL-Argument.

Example Search-URL after serching for pages with template Kiemelt:
https://hu.wikipedia.org/w/index.php?search=&title=Speci%C3%A1lis%3AKeres%C3%A9s&profile=advanced&fulltext=1&advancedSearch-current=%7B%22options%22%3A%7B%22hastemplate%22%3A%5B%22Kiemelt%22%5D%7D%2C%22namespaces%22%3A%5B%220%22%5D%7D&ns0=1

Decoded and formated:

https://hu.wikipedia.org/w/index.php
?search=
&title=Speciális:Keresés
&profile=advanced
&fulltext=1
&advancedSearch-current={"options":{"hastemplate":["Kiemelt"]},"namespaces":["0"]}
&ns0=1

Acceptance Criteria

• If the reason is advancedsearch, fix it
• If the reason is hu-wiki common.js, leave at least a comment on the problem and a way to fix it, and ping bencemac about it

Notes

• We should see if there are any search specific special cases for hu-wiki, e.g. default gadgets and stuff.
• We should check if the css classes stay the same, or if we could accidentally be hiding the search results
• These situations did not occur on de-, alemannisch, bavarian, en-, commons wiki
