Support filtering search by language
Created by: sam-lunt
This changes adds the ability to filter the results by language by adding a lang
parameter to the query (for example, to include only English results, it would be lang=en
).
I use the Arch manpages as a search engine plugin in Firefox, but one issue I have is that I will sometimes open a page in the wrong language (mostly German, since the results are sorted by language code).
