I would like to add language detection to the indexed documents. What is the best approach to do that?

Language detection depends on https://github.com/codelibs/elasticsearch-langfield
This plugin contains language resources in https://github.com/codelibs/elasticsearch-langfield/tree/master/src/main/resources/profiles
If you want to add a new language, you need to update and replace langfield plugin.
