This ZopeProduct adds Chinese, Japanese and Korean language support to ZCTextIndex.
CJKSplitter is a ZCTextIndex splitter for CJK (Chinese-Japenese-Korea) text stored as Unicode. It uses a simple, but workable, "hack" instead of trying to do real word splitting from dictionaries. Compared to a dictionary based word splitter, this results in a bigger index and more matches than necessary, but it is a cheap price to pay for the reduced complexity.
