• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang xa) or (dang ha)) hoi. hieu ((ve pham) OR (v pham)) cuc ban tinh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang xa) OR (dang ha)) hoi. hieu ((ve pham) OR (v pham)) cuc ban tinh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang xa) or (dang ha)) hoi. hieu ((ve pham) OR (v pham)) cuc ban tinh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((dang xa) or (dang ha)) hoi. hieu ((ve pham) OR (v pham)) cuc ban tinh vi cua tre*.
