Weiwei, Lucene Contrib offers a Spellchecker package that might help you with your application. The spellchecker takes a dictionary of terms (build from your search index or from some other text resource) and builds a suggestion index from those terms. Internally terms are indexed as ngrams. You can pass in a possibly missspelled term and a distance measurement function to build up a suggestion array from the suggestion index. I have no comparison how good it works with chinese text though. simon
