OK. I'll have to confess ignorance of chinese. What I gather is that words in chinese do not have spaces in between them (so it is hard for a computer to tell what is a word), but the chinese-speaker knows what the words are. Am I correct?
The way BPBible currently works for search is to consider words by splitting on spaces. If the language doesn't have spaces, then you end up with very long "words" - much longer than the real chinese word. Try putting a * before and after the chinese word. Does this give what you want? It will probably give some extra hits that you don't want, but it should at least return something. If this is what you want, I can probably put it in to do that automatically.
The bug that I saw related to the use of strong's numbers with excessive whitespace, leading to multiple spaces in a row in the index, which wasn't supported. I'll have to fix this.
God Bless,
Ben
