• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky tang ((lanh hai) or (lap tai)). hieu ((ve cham) OR (va cham)) tuc va danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky tang ((lanh hai) OR (lap tai)). hieu ((ve cham) OR (va cham)) tuc va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky tang ((lanh hai) or (lap tai)). hieu ((ve cham) OR (va cham)) tuc va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky tang ((lanh hai) or (lap tai)). hieu ((ve cham) OR (va cham)) tuc va danh vi cua te*.
