• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((nang co) or (nang doc)) hoi. thien va ((cham xuc) OR (cam xuc)) va thanh lap cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang co) OR (nang doc)) hoi. thien va ((cham xuc) OR (cam xuc)) va thanh lap cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang co) or (nang doc)) hoi. thien va ((cham xuc) OR (cam xuc)) va thanh lap cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang co) or (nang doc)) hoi. thien va ((cham xuc) OR (cam xuc)) va thanh lap cua tre*.
