Syntax: select Yes or No
CJK Mode modifies the walk and the search for better handling
many Chinese, Japanese, and Korean queries.
At index time, multi-byte UTF-8 characters are indexed as individual words. At search time, multi-byte UTF-8 characters in the query are separated by spaces, and quotes surround the sequence to make it a phrase.
This allows the query to match where spacing may cause it to otherwise not match.
