Multilingual completion suggester best practise


We use a cluster for completion suggester. It needs to support auto-complete in multiple languages. I'm looking for best practice in index design. Here are two options:

  1. a single index field for words and phrases in all languages, with standard analyzer. For instance both "solar eclipse" and "éclipse solaire" would be indexed in this field.
  2. an index with multiple fields, each for a different language and that language analyzer applied. For instance, "solar eclipse" goes to suggester-en field which is analyzed by "english" analyzer. And "éclipse solaire" goes to suggester-fr field which is analyzed by "french" analyzer.

Any suggestions, preference? Thanks.
