• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sai) or (vu dai)) ((ky tang) OR (kho tang)) van hoa. hieu ve cam xuc va dang de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sai) OR (vu dai)) ((ky tang) OR (kho tang)) van hoa. hieu ve cam xuc va dang de cua tre.
