I have some multilingual journals and Google and Google Schoolar index them only in primary language. An example:
If you go to “http://vestnik.szd.si/index.php/ZdravVest/article/view/2463” you can select in which language, Slovene or English, you can read the article.
If you go to Google and search for Slovenian title “Vpliv odprtega dostopa do znanstvenih objav v medicini: pregled tekoče literature” there is a search result pointing to the URL above.
If you go to Google and search for English title “The impact of open access on the medical literature: a review of current literature” there is search result only for the PDF but not to the URL above.
My question is how can we make it possible that Google finds the article searching with Slovene or English title?
