• Performing a fuzzy search may retrieve terms with similar spellings: so sach tu ((hanh xa) or (hanh ma)) hoi. hieu ((ve cam) OR (ve cham)) duc va thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach tu ((hanh xa) OR (hanh ma)) hoi. hieu ((ve cam) OR (ve cham)) duc va thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach tu ((hanh xa) or (hanh ma)) hoi. hieu ((ve cam) OR (ve cham)) duc va thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: so sach tu ((hanh xa) or (hanh ma)) hoi. hieu ((ve cam) OR (ve cham)) duc va thanh hai cua tre*.
