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