< p > In Presearch there are languages for the UI and regions for narrowing down the
search. If we set βautoβ for the region in the WEB-UI of Presearch and cookie
< code class = "docutils literal notranslate" > < span class = "pre" > use_local_search_results=false< / span > < / code > , then the defaults are set for both (the
language and the region) from the < code class = "docutils literal notranslate" > < span class = "pre" > Accept-Language< / span > < / code > header.< / p >
< p > Since the region is already βautoβ by default, we only need to set the
< code class = "docutils literal notranslate" > < span class = "pre" > use_local_search_results< / span > < / code > cookie and send the < code class = "docutils literal notranslate" > < span class = "pre" > Accept-Language< / span > < / code > header. We
have to set these values in both requests we send to Presearch; in the first
request to get the request-ID from Presearch and in the final request to get the
result list (see < code class = "docutils literal notranslate" > < span class = "pre" > send_accept_language_header< / span > < / code > ).< / p >
