• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky lang van hoi. hieu va cam tuc xa ((((dung dai) OR (dung dat))) or (dung tai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky lang van hoi. hieu va cam tuc xa ((((dung dai) OR (dung dat))) OR (dung tai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky lang van hoi. hieu va cam tuc xa ((((dung dai) OR (dung dat))) or (dung tai)) cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ky lang van hoi. hieu va cam tuc xa ((((dung dai) OR (dung dat))) or (dung tai)) cua te*.
