Google Search syntax to specify a language?

Question

I can read a lot of languages and am charged with doing research about software in various countries. My Google interface is in English but I often have to search pages in a particular language, and 5 minutes later in another language.

Using the Advanced Search page is very inconvenient because I always launch searches directly from the URL bar. Is there a way to specify the desired results language in the search syntax?

Note: The hl parameter is not a valid answer, it just changes the user interface's language.

Answer 1

Try the lr parameter format — &lr=lang_short_language_code.

English — en: &lr=lang_en

Ukrainian — uk: &lr=lang_uk

All language codes can be found in the source on advanced settings page.
