Unable to find pages in different languages

Hi, we ancountered similar problem to this:

Problem started when we switched xwiki to EN default language. All previous pages were in made CZ configuration and we cannot find them thrue search. Is there a way how to convert all pages to different language or configure solr to use multilanguage(btw multilang. setting doesnt work)? Thanks for help.

I also already had multiple issues with Xwiki search and different article languages - it does not really work as I expected it to, and apparently also not as you expect it to.

Maybe you can find some solution / help in these forum threads I opened regarding this:

In my cases it helped, at least.

OK, thank you. I will try.

Hi, I found solution via DB e.g.:
MariaDB [xwiki]> USE xwiki;
MariaDB [xwiki]> UPDATE xwikidoc SET XWD_DEFAULT_LANGUAGE = “en” WHERE XWD_DEFAULT_LANGUAGE = “cs” OR XWD_DEFAULT_LANGUAGE = “cs_CZ”;
MariaDB [xwiki]> exit

Restart tomcat and reindex with Solr. Hope this can help to others.
