Subject Re: Best practices for Solr highlighter for CJK
Date Wed, 02 Jan 2013 19:00:34 GMT
Speaking from experience: if you are using bigrams for CJK, do not highlight. The results will
look very wrong to someone who knows the language.

Even with a dictionary-based tokenizer, you'll need a client dictionary for local terms.
