• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (so sanh)) ((v nang) OR (va nang)) xa hoi. hieu qua cac thuc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ((v nang) OR (va nang)) xa hoi. hieu qua cac thuc va thanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (so sanh)) ((v nang) OR (va nang)) xa hoi. hieu qua cac thuc va thanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (so sanh)) ((v nang) OR (va nang)) xa hoi. hieu qua cac thuc va thanh vi cua tre*.
