• Performing a fuzzy search may retrieve terms with similar spellings: doc sach ty ((nang xa) or (nang ma)) hoi. hieu ((va cham) OR (va tham)) xuc van thanh doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach ty ((nang xa) OR (nang ma)) hoi. hieu ((va cham) OR (va tham)) xuc van thanh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach ty ((nang xa) or (nang ma)) hoi. hieu ((va cham) OR (va tham)) xuc van thanh doi cua te".
• Adding a wildcard symbol may retrieve word variants: doc sach ty ((nang xa) or (nang ma)) hoi. hieu ((va cham) OR (va tham)) xuc van thanh doi cua te*.
