I'm using Google Search and want to limit results to pages written in a language I specify.
There is a similar question How to restrict a Google search to results of a specific language? that has this answer, however I don't have access to the URL in order to edit it in my setup.
For example, to specify search results to pages written in German the URL can be modified using the lr parameter (eg. lr=lang_de) but I've tried all possible combinations of lr=lang_de in the actual search box both with and without the lr parameter without success.
How can I specify the language using an operator in the field?
