My web application supports 3 languages, English, Traditional Chinese, Vietnamese. I understand that Traditional Chinese and Vietnamese is not supported in Postgres' Full Text Search.

If I were to go ahead and implement Full Text Search, what will happen if a text search is performed using an unsupported language?

  • Define "work". You've already confirmed it's unsupported. What are your expectations? FTS won't support word stemming for those languages, it'll treat them like unknown tokens. – Craig Ringer Oct 3 '14 at 4:28
  • Sorry about that, I've updated the question – wyred Oct 3 '14 at 4:30
  • OK... so what happened when you tried it? (Otherwise: Some sample data would be helpful, btw, maybe sqlfiddle.com) – Craig Ringer Oct 3 '14 at 4:43

There are Postgres extensions to handle Chinese. Have you tried http://pgxn.org/dist/zhparser/? You can then maybe port it to Vietnamese.

    It would be better if you also answered the question. ("What will happen if ...?)" – ypercubeᵀᴹ May 21 '15 at 10:26
