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