Xwiki Solr Search how to set multiple language by default

Hi Support,

Is there way to configure “Solr search” so that the search would be performed based on multiple languages by default. Currently, the search is performed based one just one language, and I need to select other languages after the search is completed, to refine the search results.
What we are trying to achieve is that when we search something, it should be performed based in 3 languages which are English (Australia), English and English (United States). If someone can tell be the relevant configugration I need to make that would be greatly appreciated. Screenshot attached.

Thanks in advance

Hi. I don’t have the solution but I know that the default search config can be found at the location pointed to by: https://extensions.xwiki.org/xwiki/bin/view/Extension/Solr+Search+Application#HSearchUIConfiguration

Thanks Vincent. I shall investigate further.
