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