Bug#905126: www.debian.org: Website search box unhelpful for common names (e.g. Buster) in certain character sets

Package: www.debian.org
Severity: normal

A number of search languages end up with no results for contextually
common search terms, for example "debian" or "buster".

To reproduce:
 - use the search box for the term "buster" in English. There are a
   number of results including release information, news items and
   errata.
 - set the language to Vietnamese, Chinese or similar and search again
 - there are no results.

I assume that this is an issue with translations into non-Latin
character sets without hint words nearby the translated word.
