• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y dang) OR (ky dang)) xay hoi. hieu van nam xuc va anh va ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y dang) OR (ky dang)) xay hoi. hieu van nam xuc va anh va ((cua tre) OR (cua te)).
