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